Which categories have you GIVEN karma for? Emphasis on given. Don't post categories you've received otherwise we'll be double counting.

I think the categories are mostly self explanatory. By wasting space I mean anything that you feel clutters up the forum so off topic posts, 1 liners, '+1's, back-to-back posts, etc. Hi, friend is for greeting people you know from real life or k440.

My votes:
lol, interesting, hi friend, wasting space, rudeness
