I think it was a great decision to go with vbulletin as your forum of choice here. I have used vb for years now and swear by it. I have just found that no-one is even close to the power of vbulletin and I have tried them all as far as I know.

As with many other people I was furious when they sold vb and went a completely different direction. I've played with 4.0 and it's a load of crap thrown together pretending to be a forum when compared to the 3 series. I'm not even going to get into how angry i was when they changed the upgrade policy as well. Considering I probably own as many copies of vb as anyone online, this hit me hard. My bottom line is that I probably will never change to 4.0.

Now if bbpress would just get a clue and throw some development into their product, then I would consider switching. But for the moment, bbpress is a complete joke when put side by side with vb and it's feature set. I can only hope they continue development of bbpress, esp as buddypress continues to grow.
