Bring the social networking sites together

It seems like it would be interesting to have all my networking sites work together somehow. Get my facebook, linkedin and others together. Just a thought. It reminds me of the Trillian software that brought all the IM's together for me in one program. A lot of people downloaded that software and used it. It seems like it would be really useful to bring them together somehow there too. might be a lot of work, and the value would have to be immediately evident. I'll have to think about how it could add value.
