Hacker News FAQ
Are there rules about submissions and comments?
How are stories ranked?
On the front page, by points divided by a power of the time since they were submitted. Comments in comment threads are ranked the same way.
Stories on the new page and comments on the comments page are listed chronologically.
How is a user's karma calculated?
Roughly, the number of upvotes on their stories and comments, minus the number of downvotes. The numbers won't exactly match up, because some votes aren't counted to prevent various types of abuse.
Why don't I see down arrows?
There are no down arrows on stories. They appear on comments after users reach a certain karma threshold, but never on direct replies.
What kind of formatting can you use in comments?
How do I submit a question?
Use the submit link in the top bar, and leave the url field blank.
How do I make a link in a question?
You can't. This is to prevent people from using this method as a way of submitting a link, but with their comments in a privileged position at the top of the page. If you want to submit a link with comments, just submit it, then add a regular comment.
Are reposts ok?
If a story has had significant attention in the last year or so, we kill reposts as duplicates. If not, a small number of reposts is ok.
Please don't delete and repost the same story, though. Accounts that do that eventually lose submission privileges.
Can I ask people to upvote my submission?
No. Users should vote for a story because it's intellectually interesting, not because someone is promoting it.
When the software detects a voting ring, it penalizes the post. Accounts that vote like this eventually get their votes ignored.
Can I post a job ad?
Please do not post job ads as story submissions to HN.
A regular "Who Is Hiring?" thread appears on the first weekday of each month. Most job ads are welcome there. (But only an account called whoishiring is allowed to submit the thread itself. This prevents a race to post it first.)
The other kind of job ad is reserved for YC-funded startups. These appear on the front page, but are not stories: they have no vote arrows, points, or comments. They begin partway down, then fall steadily, and only one should be on the front page at a time.
In my profile, what does showdead do?
If you turn it on, you'll see all the stories and comments that have been killed by the HN software or by moderators.
In my profile, what is noprocrast?
It's a way to help you prevent yourself from spending too much time on HN. If you turn it on you'll only be allowed to visit the site for maxvisit minutes at a time, with gaps of minaway minutes in between. The defaults are 20 and 180, which would let you view the site for 20 minutes at a time, and then not allow you back in for 3 hours. You can override noprocrast if you want, in which case your visit clock starts over at zero.
How do I submit a poll?
