Actually, I would appreciate it if sane people would stay ;-) ... this forum is linked directly from bitcoin.org - if we make this a ghetto by leaving, anybody googling Bitcoin, checking out bitcoin.org and landing in the forum will get the impression that Bitcoins just about daytrading, drugs and hating government and banks. That would be very harmful to Bitcoin.
ATM, I think there's still enough reasonable people posting on the forums that the forum can be considered a valuable asset for Bitcoin.
Unfortunately it is outweighed by the image of these forums as being "official" bitcoin opinion, which quickly gives reporters the idea that we're all a bunch of crazy 4chan kids.
I would rather rename the forums to bitcointalk.org or somesuch.
