Wow, it's been forever since I've been here but I figured I should post my measly two cents, hehe.

In my personal opinion, while the reputation system had good intentions, it got to be abused fairly fast and there were too many "cliques". I would say to get rid of them entirely seeing as how greenies don't determine what someone knows and red dots could easily be thrown out on someone simply because the other person didn't like what they said, etc.

But, this is all just my opinion of course.
