I'm skeptical of the assumption made in so many of these articles: that Google will surely be annihilated by Facebook if they don't act quickly to usurp their social networking crown. Social networks come, and social networks go. Sure, Facebook is run rather more competently than, say, MySpace ever was. But it isn't at all clear how big uniques and a whole lot of people playing Farmville equate to being a contender for Google-killing internet domination. I suspect that a lot of this breathless punditry is going look very silly ~5 years from now.
