The Daily Grind: Forums you love (to hate)

With folks talking about official forums again lately, we thought we'd ask something that occurred to us in this round of talks. Sure, there are some who think official forums are the way to go, and there are others who think that official forums are all that are evil, but today we wanted to ask you what forums you thought showed the best and worst of things. Which ones do you feel are over-moderated by the people who are in charge? (Corporate or private.) Which ones really desperately need better moderation because they're just a cesspit of trolldom and wankery? If you had to pick the best forums and worst forums, who would take top honors?
