I subscribe to the idea that the eventual evolution of social networks is "openness" (eg, fb will either be killed by an open 'social protocol' or or be forced to open itself). Google's strategy shouldn't be another social network, or a closed social layer atop their current properties. They should invest heavily in the technologies that would kill fb and open them up, completely - opensocial, diaspora, etc.
