Facebook's three big challenges
Good piece ... I think the Graph search function has a lot of potential, especially going forward with more and more data. But I have a hard time seeing a future for any social network once the cool factor has worn off (outside of LinkedIn, which was never cool, and isn't really supposed to be). Google+ has some potential in the way it segments audiences in this way, but I'm inclined to think for the near future, that the younger/hip crowd will opt for other avenues to share with peers outside of Facebook, where they're "friends" with their mothers. And after a while, there will either be cannibalization of Facebook's own audience, or everyone will just have 10 social profiles.
