Does anyone know how the Karma and stuff works?

Heya, so I'm curious what I've done wrong, I went and ranked a bunch of games, left a comments and a score on each.

Admittedly I mostly ranked the unfinished games because: A) very few people look at them B) I'm on a Mac - so I can't play a lot of the games anyway. C) It's really nice when you feel like you failed, to get a message on your unfinished game that says "Wow your art is great!" or anything that values and validates the time that you spent creating.

Anyway

So I went through and I ranked several finished games, and about 30 unfinished games. This is what my game page looks like at the moment for Karma and stuff:

Karma for Feedback given: 13 Ratings given: 41.625 Ratings received: 20.75 Classic Balance: 145.1756 * Smart Balance: -30.4148 *

My "Smart Balance" didn't go up after I had ranked peoples games, so I'm not on the first 10 odd pages of games, and kinda want to get some more exposure (Who doesn't want more exposure?)

So can someone tell me what I might have done wrong, or what I've missed about how the rankings and things work? Actually, in general what do people know about the Karma system, and the Balance systems? How do they works, what are they?

Thank you to anyone who spends the time to look at this :) I really appreciate any insight that people have.

Hope you LD game is getting lots of traffic :)
