I feel the same way as the OP; having found FT only recently, I have found myself checking it often. In addition, with automatic email notification, I notice a lot more responses to threads that I have posted on popping up on my Blackberry--not close to the number of regular emails that I get, but certainly enough to make me realize I am spending a lot of time posting!
Funny how you feel like you "know" people already, just by the tone and content of their posts.
I guess it is true what they say, birds of a feather....fly together...
