There's loads of threads that are critical of UT3, including virtually every patch thread. The ones that stay though are clearly trying to help make the game better, not serve as therapy for the poster.
The UT3 forums serve a very different purpose from fan forums like BUF. Ours are the 'official' forums where people who like the game can come and read virtually 100% on-topic content. I think of BUF as the more informal gathering place for the community. There are loads of things I post over here that I wouldn't over there, and for good reason.
Maybe the analogy is the official forums are Variety and the BUF forums are Rolling Stone
