While I appreciate the enthusiasm both you Guitar and P&C have for this I just don't see how it helps the forum. The whole purpose of CRF is to provide a nice place for people to visit and talk about music and a few other things.
By adding a FB option you are actually leaving the board itself to chat, seems counterproductive to me.
Besides, how hard is it for all of you that want to talk more to add an Instant Messenger and then you have your own channel.
I will wait for the others to weigh in on this, but for now I would say it's not likely to happen.
