Perhaps, but I don't see any "dumb" people who gave ratings to people. They were all reasonable and most were informative. but would you mind naming any of these "dumb" people?
Overall I agree more with Daz, it's more accurate that the rating depends on the person who was being rated and his behavior, not the person who was rating it. Again, like I said in my previous post, I don't think it's that people are dumb and give low ratings, it's just their experience and opinion about the person being rated.
Also what's with ^?
