Hope that doesn't turn out to be the case. Forums are searchable and allow you to have a real conversation. I can go back and reference a post from 10 years ago easily, if I need to. Try doing that on Facebook. 
I agree, at least for the moment anyway. Forums have a lot to offer over Facebook. I was a member of the Amiga group on there and found myself wasting so much time scrolling through pictures of peoples various Amiga hoards.
I prefer the forums now, they have always been more useful.
