I would suspect that the whole thing including comments all vanishes, but I haven't tested it yet.
edit - I really don't care about karma, the only use it seems to have is voting people down and being able to post on the front page, and I doubt I'll ever do either of those things. I'll happily let other people be the top contributors.
The post disappears from the list of posts, and probably can't be found by searching, but it still exists and can be linked to and commented on, and any comments on it still appear in the new comments feed.
I think it also can't be voted on after being deleted, but I wouldn't swear to it.
Edit - Barring a major surprise, this post should be regarded as a worthless artifact of my impulse to do things instead of talking about them. I apologize for any time wasted on this, and would recommend ignoring it unless it is for historical purposes. I'll just stick to things I'm less bad at from now on.
This article will be edited as people post and discuss.
I believe that we need to have a clear, concise statement about the beliefs, practices, and taboos that it is rational to hold, and that we already hold as a group. To be clear, this is not an attempt to make new norms, but an attempt to codify the ones that we already hold and to get a rough estimate of the popularity/importance of each.
Core Rational - skills, meta-beliefs, and habits that enhance personal rationality
Social Rational - norms that enhance working in groups rationally
LessWrong Norms - norms for dealing with Less Wrong specifically
Common Knowledge - basic, useful beliefs to build on
Please post one phrase at a time and then give your reasoning under it. Once any idea has a common consensus, I'll add it to this article in the appropriate list.
Edited - Removed the word 'should' as someone has suggested a better phrasing. Edited again - category change, remove extra now-useless examples.
