What's the worst thing that could happen to Google?
nailer: Facebook know more about their average customers than Google does (keeping in mind most Google users don't use gmail).Facebook use this to move into search. So when I search for 'cappucino book', FB knows I mean the web framework from the context of my discussions with FB/Twitter friends.FB encourages users to make FB their first destination, users do this because it's search and their friends in one place, and why would you want anything else, when, in this scenario, FB's results are always better than Google's anyway?
