I upvote mainly because to give other people extra points and like a thanks for your comment. Though I won't give an upvote if it's too stupid. Though if too many people end up saying they don't want it then I'll just stop doing that.

No I think it is good to up-vote comments you agree with or find funny. I wish if they got enough down votes they would get deleted/blocked.. like Reddit does it.1

Yeah, I absolutely *hate* the upvote and the extra xper points I get from it too.2
