I don't think these points are particularly fatal, and they don't exactly make it hard per se to participate, just a little discouraging at times.
I take issue with his issue number one because I think the blame is placed on new people FAR too often online. The way new people are treated on pretty much every online community I've been a part of has been horrible, often downright pointlessly mean.
If we want SO askers to have good manners its our duty to explain our customs. When I answer a question from a new person I try to welcome them to SO or applaud their question (if novel), and if they worded it poorly I might answer what I think they meant and suggest better wordings to get help faster in the future.
I symapthize with the autor, but at the end of the day I choose to stay on SO in spite of all its woes because the gratitude of the answerers alone is more than enough for me.
I rarely ever get that thanks. On a decent % I don't even have it marked as an answer when it actually is.
I tend to go for the computer vision and finance questions since thats what interests me... but eh I can't participate due to those reasons anymore. I just don't care, and its not worth my time. I will however still use it to ask questions.
One of the biggest problems I see on SO is repliers tell the OP they are "doing it wrong" and not answering the OP's question. Typically you'll see some smartass reply with, "Why would you want to do that? You're doing it wrong. Do it this way, here's how."
These replies infuriate me. The OP knows what his problem is and he's asking for an answer. He doesn't need a new problem to solve. He doesn't need to know what your opinion is about solving the problem. He needs a solution.
One example: I was searching for how to solve a RVM and rails configuration problem on OS X. I typed the error message from the console into google, and found a SO question that was exactly the problem I was having. But instead of providing an answer, the most upvoted comment was to uninstall everything and use homebrew because "you're doing it wrong" without homebrew.
That's nice and all, but I've had a rails and rvm setup on my laptop for 2 years without homebrew, and, like the OP, I don't have time to set that up now. I just want to fix this one configuration error and get back to work. I quickly went back to Google and found the solution on another rails forum.
Granted, this is a problem with a lot of internet forums, not just SO. But it drives me nuts.
When I was active I would see many of the "doing it wrong" answers. It didn't seem like a big problem at the time. I always did my best to answer the question properly.
After a long hiatus, I made a new account a couple weeks ago because I didn't remember my old account. Minutes after I posted it, I receive 2 "doing it wrong" answers, someone edits my title and tags, and then another person closed in minutes for being a duplicate when it wasn't.
As one of the first people to reach 10k points on SO
(I wrote the first SO point guide discussed on Meta) no case could be made that I didn't ask a proper question. I think there are too many people with 10k points now.
Stack Overflow has become a very toxic environment.
I like those type of answers. If you are encountering an issue doing something, and there is a better way of doing it (as opposed to just solving the problem in your current method), I think it adds a lot of value to offer those suggestions.
In your example, perhaps you didn't know about homebrew and this was going to save you a lot of time, well that's great. There can still be other answers that help your specific issue, but someone has thought outside the box and offered a completely different way of doing it.
For me the value of SO would be greatly reduced if people didn't do that.
Explaining a "better" way is great as an addendum to an answer for the actual problem asked. As you said, it can be very helpful to provide an out of the box solution.
However, it is very annoying when I ask a question and the only answers are some variant of, "you are doing it wrong." Multiple times I have had to write an explanation that is longer than my actual question to convince people that I actually do want an answer to the question I asked.
If you really think you understand my problem better than I do, based on a simplified explanation, awesome. I would love to hear a better way to go about what I am doing. But please, try to answer the actual question first (or at least say you don't know the answer). There is a slim chance the "better" way is not actually workable in the real world scenario.
I get those sorts of answers most often because the real problem is too complex to give as the example, and I simplify the example down to what's essential to my question. Then, there's often a better way to solve that particular example, which wasn't the goal. I often even put something in like "I know you could solve the problem in this example with X, and I'm not looking for those." And people will still say "Why are you doing it that way just do X". That gets pretty infuriating.
This is so so true! The problem is that the person saying "you're doing it wrong" often has no clue what they're talking about. I daresay Rich Hickey, Bjarne Stroustrup, or Brendon Eich would get told they're "doing it wrong" too.
When people ask questions online, far too often the person answering assumes that whoever asked the question must be a complete idiot. There are plenty of topics in which I would consider myself an expert, but I still get treated as if I know nothing about the subject. (I've noticed the problem also manifests itself in academia -- the more prestigious the academic institution, the more everyone assumes everyone else is "incompetent by default").
I agree, I find there can be quite a lot of groupthink on SO in that kind of way. For example, the top answer to most questions about any kind of optimisation ends up being some patronising thing about "you should profile and only optimise once you know it's a problem". Well, I wouldn't be asking for advice on a web forum unless I knew it was a problem - just answer the question, please!
This may touch on some points I've already addressed  but I have to say something.
I was a frequent contributor to StackOverflow  but have largely stopped for a number of reasons, the most important of which is I got a new job that took up much more of my time.
But another reason is that for me, as a (then) frequent answerer, it got a whole lot less interesting. This was due to two factors:
1. A lot of the low-hanging fruit had been answered so the questions became increasingly esoteric such that you were less likely to simply know an answer and had to spend more time researching. That extra time meant you were also less rewarded for the answer because less people were in a position to state that it was correct or not (if you consider karma a "reward"); and
2. The ceaseless campaign against "interesting" questions due to increasing closure due to "subjective and argumentative" and the fragmentation of SO into the many StackExchange sites (causing a lot of questions to be migrated).
There are three basic errors that Joel has (and Jeff had) made (IMHO):
1. Over-emphasis on editing.
In my mind there are three groups: askers, answerers and editors. Jeff & Joel made statements about editors are important and how editing is super-important, basically trying o elevate it to the same level as answering questions.
This is a problem.
Editors are the bureaucrats of the StackOverflow ecosystem. The bureaucracy is expanding to meet the needs of the expanding bureaucracy . The more editors you have the less each has to do. Rather than doing less, the kinds of people attracted to this kind of function prefer to simply create work for themselves.
What's more, from Meta StackOverflow, from interacting from the people who edit a lot (and answer very little if anything), this simply reinforced my view: these are the kinds of people who destroy communities.
Those who can, answer. Those who can't, edit.
I've seen many spurious edits to many of my higher voted answers. Some capitalize something. Others come along and uncapitalize it. I've seen people come and add lines to my answers saying I stole it from someone else (seriously).
The net result is virtually any highly voted answer I have has been edited into community wiki oblivion. That creates a strong disincentive for me to spend time coming up with a good answer: I'll basically get limited credit from it and then have to watch as wanna-be editors essentially vandalize it.
The other thing these people do is close questions on the drop of a hat. They, as a group, tend to have an incredibly festidious nature when it comes to the enforcement of rules. They constantly seek some purer, higher standard and don't quite get that those rules are guidelines that are a means to an end and not an end in themselves.
2. "Subjective and argumentative".
Jeff and Joel from the outset wanted to prevent flame war type questions, the kind of questions that have no definite answer. Questions like "Is Ruby better than Python?" That's fine but it's been taken too far, in part by the very editors I previously mentioned.
Questions like "Should I use Angular.js or Ember.js for developing a CRUD-type Web application?" would be shut down in a minute. But the extra context matters. You can answer that question by giving a list of comparative advantages without being necessarily biased or inflammatory. That's actually interesting content, particularly if you're trying to decide between a number of new technologies, languages, etc. But alas SO seems keen on shutting that down; and
There is another thread today about the difficulty of music classification . The same goes for Q&A. Hierarchical classification schemes are too limited for Q&A. There are SO questions that have bounced around between a number of SE sites for this reason.
Just look at the Stack Exchange sites . If I want to ask a question about being a programmer do I ask on OnStartups, on the Programmer SE or elsewhere?
The pragmatic answer is that there are some question that naturally fit on several sites. Yet the hierarchical pigeon-holing with esoteric and often subjective rules means it's harder to find content, it's hard to find where to place content and newbies inevitably get chastised for posting on the wrong site.
There is a reason tagging exists and is successful. Describe the traits of the question or, better yet, figure it out from the content, and show it when it's relevant to someone. Don't make me hunt across sites for it. That's a ridiculous solution.
I predict you'll see the rise of more tagging-oriented (at a higher level than say Java or C++) and automatic classification Q&A sites in the future.
With that out of my system, let me address som eof the points the OP specifically raised:
> The Eternal September Issue.
This one annoys me. And I don't mean new people. The negative reaction people have to them (eg ). When a community starts chastising newbies, that reflects badly on the community, not the newbies.
> Down voting as a means of closing a question.
The one part of downvoting I don't like is people use it as a means of saying "I disagree with this" (on purely subjective grounds), which is not the intended purpose. That problem seems to be nearly universal with voting systems (even here). The one good thing SO does is "charge" you for downvotes. That alone stops it being a huge problem (IMHO).
> This is another one of the odd cases on StackOverflow. A few of the “Exact Duplicate” questions are not duplicates due to minor, but important, differences.
True. The problem here again is that you have editors deciding to close things that they don't necessarily know anything about. The same problem infests Wikipedia (deleting articles on "notability" grounds).
> The value of reputation: After the global recalculation, the site’s creators made a bold statement that participation is not valued on the site.
I actually don't know what this is referring to but then again I've been largely inactive. There have been several recalculations though (eg question upvotes from 10 to 5 karma). I don't really have a problem with this. If you're too obsessed with your karma, you're focusing on the wrong things. And I like that the same rules apply to everyone (eg it's better than question upvotes before X are 10, after X are 5).
I worried when SO took VC money that they were going to turn something that is very successful in one segment and ruin it with attempts at making a general Q&A platform. 2+ years on I'm still failing to see traction in the SE sites beyond SO. This may yet still become a problem.
Perhaps the simplest answer here is that SO isn't a "community" as such. It went with the Q&A format (over, say, forums) to discourage discussion. People often criticized it for making discussion hard when that was kinda the point.
I certainly never went to SO to hang out. Some do I'm sure. The focus is (and should be IMHO) on the content not the community.
I haven't logged onto SO in months and not likely to ever log on again. The only time I ever end up on SO is due to a Google search and almost invariably the topic has been closed due to the "closed as subjective and argumentative" reason.
The other day I was doing some searching on the use of express in node.js. I think I found about 10 relevant and useful threads of which I think only 1 was still open. All the other threads I actually found very useful had been closed by some moderator. Subjectively, I think this is a very typical ratio.
I agree, my first question on SO was: "What is vert.x and why is it useful?" was basically downvoted to hell, and then closed and eventually deleted.
It didn't leave me with a great impression of the community TBH, and felt overly draconian. Of course I didn't make a big scene about it, and will still contribute now and then after having adapted, but I think that's a shame in a sense, because often broad and open questions generate a lot of useful discussion.
StackOverflow has been very clear that they don't intend to be a discussion site. Even if you like subjective questions, that doesn't mean that a site shouldn't be able to specialize in something else.
I like basketball. But I wouldn't expect stackoverflow to allow basketball questions.
This isn't a judgment on the value of discussions... but there are other sites for that.
Asking if a question is subjective may, itself, be a subjective question.
Communities of Practice (Lave, Wenger) are held together by sharing a common repertoire of practices, and opinions. Newcomers may want to explore these shared opinions. SE is obviously not a place where they can do that, so I end up agreeing with your final sentence.
Just because you like something doesn't mean that it has to featured on Stack Overflow. Same as politics discussion on HN, many might want to debate Romney vs. Obama with the HN folks here, that doesn't mean HN has to tolerate that and turn into another Reddit.
I don't understand all the complaints about having discussions that can easily degenerate into flamewars with thousands of "answers" on Stackoverflow. If it's moved to a Stackexchange with less traffic, go hang out there and make it a better place.
Ah, the slippery slope argument. "If WE aren't tight on the rules, the site will quickly degernate into a useless mess." Where have I heard that before? On Wikipedia. It vastly overstates the job of those that delete stuff. They aren't the ones creating a great site. Those that ask and answer questions are.
My experience with online communities tells me that the slippery slope in this case is very real. When new and immature folks generate content with back and forth among themselves(voting each others' comments up), the old timers simply pack up and leave since the site doesn't interest them anymore. Happened to Reddit right before my eyes.
So why not use programmers.stackexchange.com for such discussions? The more people use it, the more active it gets. Stackoverflow has already made their opinion clear on this.
It's pretty much guaranteed that any system with a privileged regulator (moderator, editor, whatever) class will bog down in the long run. The basic problem is that regulators get credit (however that gets measured in a particular community) when they regulate, not when they leave things alone or reduce the amount of regulation. Thus there's an incentive for regulation to increase even when it may not be needed, and indeed even when it is counterproductive.
There have been a couple of suggestions in science fiction that would be interesting to see someone try. Heinlein suggested a special branch of government whose purpose was to repeal laws and regulations promulgated by the other branches. Frank Herbert went to an even greater extreme, by having an quasi-official "Bureau of Sabotage".
Perhaps online communities should have a separate group charged with reversing the decisions of editors/moderators/whatever they're called, with no discussion or appeal permitted.
Thinking through the likely consequences of "volunteer bureaucrats" should send a shiver down the spine of anyone designing a crowdsourced resource. Even without a formal system of recognizing the work such people do, their own gratification inevitably rests on wielding the power they have.
So, yes, a system of meta-moderation, and preferably one that is mechanical and resistant to being gamed, is needed. As fascinating as it is to see emergent cultures in Wikipedia editing and reddit moderation, it ends up being dysfunctional, and that doesn't serve the goals of the communities from which those sites derive their value.
Let's give a standing ovation for this needed criticism of SO. I just hope SO opens themselves to hearing it.
I've said it before, I'll say it again -- the creators of StackOverflow don't know what made the site successful in the first place.
SO is successful because it's an experts-exchange.com clone without the pushy subscription model plus a few social voting features added in.
The problem also is that the site was essentially complete within the first year. But there are still people on staff and they took a bunch of VC money. The people on staff need to do something and the VC money needs to be spent.
So of course they start meddling with their already completed product. Editing is now seen as an Important Thing and many red herrings like "keeping the site from becoming Reddit" are trumpeted in order to justify this meddling.
Nonsense like "Gorilla's vs Sharks" are trumpeted in order to justify this meddling.
And even worse than the meddling on the new stuff, they go back and close old questions, even ones that have been quantifiably validated by the votes of hundreds of people. I'd actually bookmarked many of them, only to find them mysteriously closed months later.
The global recalc happened arround Feb10. They applied the new policy retroactively. My reaction was ffs.. how can I actually get credit for the participation. Theres no value in supporting the site other than the reputation you have. The reputation should reflect on how helpful you are. The karma you get there is helpful to demonstrate to employers how well you can help others, thats a little difficult to explain how your score just got deflated.
Asking valid and relivant questions is important, it contributes to the community. However, it is acceptible to reward answers more. [Since they do take more work]. Its their site (despite most of the site's value is derived from the work of the users), so their determination on whats important is up to them. However, they applied this retroactively. That irked me, if they had a system where they applied it after x date, that would be fine.
That decision told me... hey tomorrow they can just decide that all users with name x, y, or has numbers in the name can go bankrupt on reputation.
That was the only truly contentious user impacting change they've made over the four years the site has been around. I think your last sentence is a nonsensical justification to complain.
If anything many of the recent changes have been to make the site more inclusive such as suggested edits, better review processes and so on, so that users who are still on their training wheels on the way to the the 10k and 20k tools can practice "community moderation" under the guidance of more experienced users.
'If you're actively participating on Stack
Overflow, we now have another way to convert
those slices of effort into something that
actively furthers your professional goals
Stack Overflow Careers.' Coding Horror.
Its easier to make a comparision of accounts if the employer is using Stackoverflow Careers. But if you have a general reference to your rep amounts on your resume thats much more difficult to explain why you don't have a decent amount of rep, or if the employer is clever.. they may notice a difference in rep from an older copy of your resume and current.
Agreed. The questions that are closed are the ones that are usually helpful to me, like best way to make money on Android, etc.. The questions that aren't closed tend to be stupid stuff you can lookup in the docs anyway. Site just isn't useful to me due to the heavy handed mods.
It's clear that SO adds a ton of value in general, and I've frequently found it useful when I'm working with a new and unfamiliar piece of technology and can't quite figure something out. I've found it to be sort of annoying as an answerer, though, and don't really hang out there looking for interesting questions to answer anymore.
The biggest problem is that some people treat it like a game of Jeopardy, except with no penalty for incorrect answers. This is especially true when the questions are dealing with weird corner cases in languages or libraries - it often looks like there is an obvious answer, but it isn't always so simple.
I used to take the time to get the code running on my machine (if it was simple enough), figure out what was wrong, fix it, and then take the time to try to educate the person asking, rather than simply telling them what code to paste in to fix it.
This takes time, and in while I was working on it, you'd have someone come in, and blurt out some guess as to why it wasn't working, then edit their answer a bunch of times and maybe eventually get it right. I don't know why, but it always bothered me to see someone who guessed around (and maybe looked at better answers in the meantime) getting credit for really sloppy work.
I guess I don't know how you'd fix that, and it doesn't seem to be a big enough of a problem to keep the site from being useful, but it is still kind of annoying.
The incentive for quick sloppy answers comes from the bias of voters towards what's already upvoted, which could be fixed just by showing them the answers in random order without the scores. Maybe change the display mode after the page settles down some, by some measure like time passed, pageviews, or answer accepted.
I agree there's a problem, and used to participate anyway because more fun or interesting questions were getting asked early on; I never seem to see new ones when I peek in nowadays.
Added (heh): people also vote for sloppy answers just because they sound good. I don't know what to do about this -- perhaps you could try to estimate a voter's average vote quality, and weight them.
My other problem at the moment is that I am working on some objective-c stuff and SO is mostly useless for finding answers. Being new to the language and the APIs, I am sometimes lost and trying to get my bearings. A few questions I've submitted have either been closed or ignored. Only one really got a good answer, and when I tracked down the author I found he is very skilled and helps out lots of people. But there only seem to be a few people like him.
And by the way, if you're in SF and know objective-c, I'll buy you a couple beers in exchange for walking me through a couple things.
Although I often feel stackoverflow is less useful than it used to be, without a doubt many of my google searches are answered immediately with a stackoverflow post at the top of the results, removing the need for me to ask a question in the first place. It's easy to discount how important SO still is to my developer learning workflow.
I'm finding I'm starting to go back to mailing list for niche programming topics (e.g., a specific framework or library) because nothing beats getting an answer from a top contributor or owner. Most people don't sit on StackOverflow all day waiting for questions, but they will respond to e-mails that pop up on their mailing list.
> Down voting should be a way of saying, this is either wrong information, misleading, or not helpful.
Many people claim that down-voting should only be used in very specific cases, but The Stack Overflow guideline seen while mousing over the down arrow is "This question does not show any research effort; it is unclear or not useful." I think that (especially the insufficient research part) is pretty broad.
I argue about this with Shog9 [a newer mod] on meta. His response was that it should be dead on, completely right [despite hidden assumptions]. Even if it was correct [and maybe not related: lets say that someone is asking about how to opt c++ code, most advice will say to improve the design, but an answer on gcc opt flags is relivant just not exactly what was asked] it should be downvoted.
I called him out on that insanity, he was a big member on CodeProject, as was I. His excuse for that "codeproject turned in a shithole, lets not make this place like that" [not exactly what he said but it sums up many of his responses].
As a reader, I find SO quite useful. From the outside, however, the community appears particularly unwelcoming. For lack of a better term, it seems as though participants are walking on eggshells. Standards are enforced extremely rigorously, quite possibly to the detriment of the site as a whole.
I have not yet contributed, in no small part due to the above. I don't need SO karma to prove my knowledge in a given domain, and therefore my only reason to actively participate would be if I find it intrinsically rewarding - which does not currently appear to be the case.
I get annoyed when I go looking for the answer to a particular technical question and find that the most precise related question has been closed as "too specific", whatever the hell that is. Well, yeah -- after questions about geometric methods and proper etiquette are answered, you get into more specific stuff.
I do the only thing I can. Upvote the question (which can still be done on closed questions), and tell the questioner it's good, and the moderator is being an ass. Which they usually are.
The kinds of questions that annoy me aren't "do my homework"; they're real questions that focus on specific issues that I'm encountering and wasting time on. Some brownie-point seeking moderator is engaged in exactly the type of behavior that other comments note.
The real value of an SO answer is probably best approximated by how many people it helped. In my experience, SO is incredibly useful when I'm learning a new language or framework, and I want to quickly blast through hurdles caused by non-intuitive syntax or functionality. In those situations I'm on there almost constantly. For popular languages like Objective-C for iOS, there are thousands of people who are in that same situation.
Surely there must be a way to capture the value-added for all those thousands of people in the reputation system? Many people get to these answers from google, so it sounds like a simple matter of pinging them to (sign-in) and upvote the answer that helped them out.
If, on the other hand, as the author says SO is no longer actually values reputation, and is screwing with their algorithms accordingly, that is a serious problem. Not sure what can be done about that.
> Surely there must be a way to capture the value-added for all those thousands of people in the reputation system? Many people get to these answers from google, so it sounds like a simple matter of pinging them to (sign-in) and upvote the answer that helped them out.
This happens if you're already logged-in and got to the site through a Google search (although only under certain circumstances—I think you have to have not visited SO in the past few hours/days?)
> If, on the other hand, as the author says SO is no longer actually values reputation, and is screwing with their algorithms accordingly, that is a serious problem. Not sure what can be done about that.
The only changes to the reputation system that I can think of are:
I was quite keen on SO at first, but have gotten much less so over the past year or two. The most recent incident that really put me off was a month or two ago when I found what I considered a pretty ideal SO question; ie. a "how to do X programmatically". Someone (a relatively new user) had already commented that it was a dupe of another question which it clearly wasn't; several of us simultaneously corrected him, and all seemed fine. Until a few hours later when some drive-by mod arbitrarily closed the question as a dupe; they obviously had enough ninja power to do that off their own bat, but it needed four or five of us to vote to reopen and the last I saw it'd only gotten to two or three. The original questioner seemed fairly demoralised by it; I wouldn't be surprised if he didn't come back.
I'm sure there are plenty of other cases of good moderation, but to me it highlights a serious problem with the site. One loose cannon (who I can only assume either was a badly written bot, didn't speak English, or was just trolling) and one overactive mod managed to ruin that question for everyone, and the rest of us had little power to really help.
I don't know what the answer to this is; it bears a lot of resemblance to Wikipedia, and they still struggle with it.
I completely agree with the Eternal September point, or maybe it's just a problem of non-makers tearing down others instead of doing something more worthwhile.
I recently solved a tricky bug in some Java code that we eventually realized only happened after de/serialization upon server restart. Seeing no related questions on SO, I took the time to create a self-contained test case as part of a question and also to answer that question with a solution that showed how to use reflection to set the value of final fields.
For my trouble, several SO members trolled or ridiculed me. This doesn't exactly encourage future participation. My time is too important to waste it helping self-important, ungrateful jerks.
I was an active user once, but got tired and bored by the recent flood of 'questions' that are best answered by "Learn how to use a debugger" or "RTFM". I'm especially annoyed by people pasting a rather large chunk of code with a vague description of the problem and expect others to debug it for them.
I even have moderator privileges, but I don't have the time or desire to bother anymore...
I also started a discussion on meta-SO about "fix my code" questions with a concrete proposal , but didn't get anywhere. The most operational (and upvoted) answer/comment there was that the "close question" system was intended for this and that no other mechanism was needed. Well and nice, but maybe we'd then also need a filter that would filter-out questions with 2 or more votes to close. (You could still opt-in to see these questions, by they shouldn't be on the frontpage by default.)
I think the "we will teach you a lesson when you disagree" attitude is pretty juvenile. It also seems like it's bad for business. People won't ask questions so there will be fewer search results directing people to the site.
The community expects folks posting questions to have done at least a tiny modicum of work before asking for help. You even admitted in the comments from back then that:
"@event_jr. Screw you. I'm looking for a quick elisp solution not your opinion. No one is doing my homework. I'm just getting a answer to something that I thought would be useful. Thanks correct. I don't want to put a lot of work into it. I have a Perl solution that'll do."
"I did zero, zippo. No work before asking."
So you know, you only had yourself to blame there.
I'm not debating the value of my question. Between two different accounts, I've asked over 150 questions since the beginning. You can have whatever rules you want. I disagreed and quit StackOverFlow. I'm not contributing to the site. I've been on the Internet for over 20 years. I know where and how to get answers.
At the moment, I'm pointing out the the juvenile "beat downs" that happen certainly don't make the site appealing to a certain group of people. I'm sure that I'm not the only person who has quit in frustration.
Btw, it's great that you found my deleted comments. Can you also include his snarky comment to which I'm responding?
"Closed as not a real question" is really a ridiculous reason. You have asked how to implement a transformation of a well-defined input to a well-defined output using elisp. If that's "not a real question" by SO's standards, then it's about the time the site dies...
Slightly off topic, but am I the only person who cringes when people complain about duplicate posts?
Can't think of another issue where the angst is so disproportionate to the underlying problem.
I know, duplicate posts take up system resources, and we all remember when Technet and Usenet were DoSed by one too many duplicate posts (or did that not ever happen?). But duplicate posts also make common issues /usability problems more visible, and illustrate how terrible every forum's search is.
And besides, we've been trying to stop duplicate questions in tech forums since what, the first BBSes in the 70s? It hasn't worked, the fight is not worth fighting.
That's why duplicates on Stack Overflow usually aren't supposed to be deleted. They're supposed be closed with a link to a canonical question, so that all answers are available in one place, but they'll remain open to help people who are searching.
the most annoying thing, for me, is seeing obvious newbie questions closed as (inexact) duplicates of some other question, when it is patently clear that the questioner does not have the ability to apply the other question and its answers to his problem.
Because of this the policy now is that some duplication is good. Though a lot of users are still rabid about closing, I always try to answer inexact duplicates, and if the their title doesn't lead to duplicates, point out the things they should have searched for (ie, object picking, hit testing and point in path are three names for very similar things)
I find it weird that people use Stackoverflow as a community where they hang out and spend time. The obvious way to use Stackoverflow is when you're having trouble figuring something out you get there via google. While doing your research you might come accross an unanswered question that you know the answer to so you write it up. That's it. It's a very useful site but there's no need to get emotionally involved with the reputation score.
As far as using the score to get a job, I don't buy it. If you're actually good at some topic you will be able to get a job regardless. If I was hiring someone who was pushing their super-high Stackoverflow score I would be suspicious why they spent so much time gaming a dumb score on a website instead of building cool stuff.
No-one has ever suggested that SO rep alone should be used solely to judge someone's skills when hiring. Then neither would the contents of your github or bitbucket repo (after all how do you prove that the code in the repo is yours?).
SO rep is just another small nugget of information that may be useful to potential employers, and if said employer is using the SO careers site, your Careers profile is linked to your SO profile page.
I mention in my "other activities" section of my CV that I participate in the site, but I certainly don't make a big deal about it, and especially the rep part.
Early on Stackoverflow was a great place, because you could ask any programming related question and you basically got a good answer or someone pointing you in the right direction quickly. Nowadays you first need to figure out where to ask. For some reason too granular classifications seem to be connected with programmer mindset. Also earlier lot of subjective and interesting questions were allowed, nowadays anything like that is closed quickly.
That said, nowadays I mostly browse ux.stackexchange which isn't as nitpicky yet.
As apparently the lone voice of dissent, I like to say that I find the StackOverflow moderation to be helpful and increase the quality of the site. I suppose it's not a coincidence but I don't find it difficult to participate at all.
For me the reason it's difficult to participate in is completely different. I originally signed up with my own OpenId server run on a static IP address from my basement rack. When we switched ISP's, we went with a normal account and moved most of our servers to Linode. I didn't bother moving the OpenID server (I'd forgotten about it) but about 7 months later, I lost the cookie for SO and that ended my ability to log in.
I have to contradict the article's assertion that karma's were dropped by the rebalancing ... I've been amazed at how my better answers have continued to receive up-votes and I think my reputation is about 1000 points higher than it was when I last participated.
Lots of people don't accept answers that are correct, even if we've had subsequent discussion and elaboration of the answer :( I have a few open answers telling people exactly how to do things, and they've thanked me for my answer (and in one case I won a bounty) but my answer is STILL not accepted.
