One of Google's strengths is innovative strategies to counter employees who are leaving just for the sake of novelty, also knows as their 20% projects initiative. From what I hear, this is no longer enough to keep their employees there, especially the ones who have already made their money from GOOG stock. I posit that this move is as much to address that as to change how they buy startups (they were already doing that a lot even without a formal VC arm)
