I've been knocked down quite hard with a karma score and had someone reply to my comment with what I had just said, and get voted up like crazy. And some days I'll get negative karma for something that got positive the day before.
It would be interesting to see if comment karma scores changed by hiding the score from your view before you upvoted someone. That would eliminate "groupthink" because you would not know how many other people voted for a comment until after you upvoted (or waived your right to upvote).

"HN is filled with Bipolar people." -- No. You cannot upvote a comment you previously downvoted. HN is filled with people that maintain a variety of opinions.
Man, when something is potentially ironic, it's really confusing whether it is intentional or not. Oh well, I all ready voted as if it were intentional. Sorry mikeyur.
Why do people feel the need to continue voting down a comment like this that is below 0? Clearly mikeyur made a mistake (HN could very easily prevent these types of mistakes). Voting it down to 0 seems sufficient.
But a few times I've been surprised (both ways) by the karma score, so either I don't fully know the "group think" here - or there isn't one.
