I like NeoGAF because it's more laid back than here. The moderation there isn't very strict, yet for some reason the trolling and baiting aren't big issues there the way it is here. Usually, when a commenter trolls are tries to ruin a thread, people gang up on him and show him his actions aren't welcome. Which means people think twice before shitting things up.
Anyway, what I like most there is the fact that a lot of developers take part in the discussion, making it easy to interact with actual members of the industry. It's especially neat when you get to interact with a dev that made a game that you enjoyed.
