I'm surprised that most of these are so small. There must have been others? (I excluded the boring or empty ones.)


Added. Thanks!

The submitter posted the title that the article had at the time. Then the BBC changed it there. Then a moderator changed it here. And then a moderator (this one!) marked this subthread—which was stuck to the top of the page, gathering mass and choking out anything interesting—off topic.

I don't fault the comment for that so much as the upvotes, but downweighting top subthreads that are off-topic and/or generic in uninteresting ways is probably the highest-leverage intervention that moderators do here. Unfortunately it requires human intervention, and we don't see all the threads, so if anyone notices an off-topic or generic top subthread before we do, letting us know at hn@ycombinator.com is super helpful.


Could you please stop creating accounts for every few comments you post? We ban accounts that do that. This is in the site guidelines: https://news.ycombinator.com/newsguidelines.html.

You needn't use your real name, of course, but for HN to be a community, users need some identity for other users to relate to. Otherwise we may as well have no usernames and no community, and that would be a different kind of forum. https://hn.algolia.com/?query=community%20identity%20by:dang...

It's much shallower than that. You posted over-the-top language about a country, complete with Nazi references. Please don't. It makes internet threads really shitty.

If you don't think "So they're not putting people into ovens yet, but besides that" is flamebait I'm not sure what else to tell you.


I've banned this account for using HN primarily for ideological battle and also for the trollish username. We've asked you many times to stop the former, and you seem to have ignored my question about the latter (https://news.ycombinator.com/item?id=25362566).

If you don't want to be banned, you're welcome to email hn@ycombinator.com and give us reason to believe that you'll follow the rules in the future. They're here: https://news.ycombinator.com/newsguidelines.html.


Please don't take HN threads into nationalistic hell on top of the ideological hell we are all enduring with topics like this. If you want to make a point about international variations in language, that's fine, but turning it into a whole separate flamewar is not cool.

https://news.ycombinator.com/newsguidelines.html


> It's hard to argue that HN is still really focused on startups.

I hope so! That was the intention behind its name change in 2007: https://news.ycombinator.com/hackernews.html.


It's certainly an interesting topic. It's not good to submit home pages of blogs or content sites to HN though. The discussion has nothing to sink its teeth into beyond the generic theme of the site, and that leads to shallower discussion.

https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...

It's much better to submit the most interesting article from a site, the one that goes into the most unexpected specifics. I looked at a bunch of the articles on this site and they all seem pretty lightweight, unfortunately.


There's probably an obscure and wonderful web page about that which has never been submitted to HN before.

Please don't take HN threads into religious flamewar. Last thing we need here.

https://news.ycombinator.com/newsguidelines.html


Nationalistic and ideological flamebait and flamewar are not welcome on HN. This was well over the line. No more of this please, regardless of which nations or ideologies you have a problem with.

https://news.ycombinator.com/newsguidelines.html


Would you please stop creating accounts to break HN's guidelines with? Obviously we have to ban such accounts. Continuing down this path will get your ban account banned as well, so please don't.

If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and taking the intended spirit of the site more to heart, we'd be grateful.


We've banned this account for using HN for religious and nationalistic flamewar. Definitely not what this site is for!

If you don't want to be banned, you're welcome to email hn@ycombinator.com and give us reason to believe that you'll follow the rules in the future. They're here: https://news.ycombinator.com/newsguidelines.html.

The GP shouldn't have included that flamebait, but please don't respond to flamebait by bursting entirely into flames. That's going the wrong way down a one-way street, since we're trying for exactly the opposite here.

Of course it's a highly emotional topic and justly so, but one of our intentions here is that we all work on self-regulation around this kind of thing (e.g. processing strong reactions internally before rushing to comments) - not really for ethical reasons, but just because it's the only way to avoid the failure-mode end states of internet forums.

https://news.ycombinator.com/newsguidelines.html


That flamebait at the end led predictably to a flamewar. Please do not post like that again.

https://news.ycombinator.com/newsguidelines.html


That's actually against the site guidelines, which ask you to "Assume good faith."

The reason is that it's hard if not impossible to accurately assess other commenters' intent, and there's a strong default on the internet to assume bad faith. We all need to consciously counteract that if we're to have substantive, thoughtful discussion.

It's true that some commenters behave abusively in ways that make assuming good faith impossible, but (a) I doubt that was the case here, and (b) the guidelines ask you not to reply in such cases, but rather to flag the comment and/or email hn@ycombinator.com.

https://news.ycombinator.com/newsguidelines.html


I believe you! (And now that you mention it, it's pretty obvious.) Unfortunately those often don't come across on divisive topics.

Personally I've always considered Hop on Pop underrated as a Dr. Seuss classic.


The author mentions a 2012 version of this post. It was discussed here:

Girls and Computers - https://news.ycombinator.com/item?id=3757796 - March 2012 (84 comments)

It is by no means limited to the Indian political right.

I haven't read that essay since it came out, but I always found that it interesting, because non-identification is a well-known spiritual teaching, indeed a well-known Indian spiritual teaching — but pg seemed to get at it from first principles.

That's a separate question. If you'd like to make a case that the article is off topic for HN, we're always open to hearing that sort of thing. You should make an argument in terms of the goals of the site, though, not just name calling, which is usually a way of expressing ideological dislike.

Please no. It can only lead massively off topic, and is certain to turn nasty. We're trying to avoid that here.

https://news.ycombinator.com/newsguidelines.html


Please do not take HN threads further into flamewar.

https://news.ycombinator.com/newsguidelines.html


That can only lead massively off topic. Please don't take HN threads into generic political flamewar.

https://news.ycombinator.com/newsguidelines.html


Yikes. Please keep flamewar comments off HN—especially classic ideological battle stuff. Also, please note the site guideline against calling names.
