It would be nice to know who will just give everyone they play an average rating of 3stars no matter what occurs in the game and in chat. Some people are just bitter all the time and give lower ratings just because they are filled with anger. Averaging what players rate others will:
a) give a heads up to avoid playing against the angry person, and
b) encourage more accurate ratings.
Looks like a win-win, and with so many I'll spirited people emboldened behind the keyboard, maybe this will breed some kindness on this website.
