I'll be honest and say I don't 'get' or understand it all. I'm not trying to be overly cynical, I just don't see a way it could be reliably implemented on the same scale as Facebook.
I don't see how grandpa Jones is going to get his photos to his grandkids using his swanky new iPhone.
I'm very much sticking with the Facebook analogy as it's frigging huge and surely the point of any social service is to get the masses involved.
