related question: i've seen comments here that have, say, -2 points. if you can only vote up, how is it possible for a comment to ever go below one point? my guess is maybe you get a down-vote button once your karma goes above a certain score?

You've got it, but you can only downvote comments. And you can't downvote replies to your comment.
