The other mainstream bears forum, chicitysports, is so terrible with the bickering and insulting. I only lurk, but it seems very cliquish. Constant fighting in every single thread.
It's tough to start up an old school forum like talkbulls now a days. Reddit and other major social media platforms have hurt the old school forums. Only the great ones (Soxtalk) survived. RealGM has held up as far as Bulls and basketball forums go.
