Why Google wants to talk in terms of Facebook vs. Google+
It's nice to innoculate the ideea of Google+ vs Facebook , it's like i would talk about the problem of me vs. Arnold in a mister univers contest (i'm more fat than slim lol )
Imo its a good marketing move to compare yourself to the greatest when you are nobody, people may think you are in the same league with your opponent.
