What's to improve, 
Fordim?!  If you got negative reputation points, I can only imagine that someone was disagreeing with your point of view - not necessarily the best reason to rate someone down; the negative box says "I disapprove", not "I disagree". 
I do try to give rep whenever I read a good post, whether it be RPG or a Books discussion.  Sometimes I can't, since there are people who write such good posts so frequently that I can't seem to spread fast enough to keep up with them.  I'm fortunate to be on an RPG with excellent posting quality, so I have no problem giving points for individual posts there.  I think it's a problem that RPGs are not as widely read as the discussion threads, and I know I can keep up with only the ones I write in, for the most part. 
On the whole, I find that I give points more often than I receive them - isn't that called "blessed" in the Bible?
