Seems to me the services facebook provides would be better provided on the operating system. It would have to be built in though - people don't want to download anything.

If Apple got into the business of social networking, they could fracture the community.

I stopped using facebook much when it got bloated and slow. This tends to be what always kills these massive sites. Someone will figure out a way to do better than them and the internet elite will jump shit and eventually there will be more than one facebook.
