Yeah, which other commuting forums exist? And by 'exist', I mean something that gets more than 5 new messages per week.
When BF did it's conversion to VB4 a few weeks ago, I really didn't like the new layout and looked for other bike forums (specifically, commuting related). I found some, but they were all dead. There are a few road cycling forums, but they're a different breed. Those guys don't care to hear about commuters dropping roadies on their way home from work.
Besides, I noticed the usability of the new design is getting better. Those little improvements have been making BF feel like home again.
