This explains why the goog wanted so badly a piece of facebook. And why Microsoft would pay at any wacky valuation for FB to keep it out of teh google. Facebook is the singular major social network not participating in google’s new scheme.
At the same time though, it cuts out at the knees the fundamental (would be) game-changing advantage of the facebook platform: the idea that someone should be able to build a social app or someone should be able to use a social app without the redundancy of setting up a new profile page, another buddy list, another messaging and comment system etc. (not to mention the viral adoption and network effect advantages that have made some facebook apps the most rapidly adopted software apps ever).
Meanwhile at long last, Google combats microsoft with it’s own operating system… a social operating system for the new web.
