This article fails to support it's own thesis. I'm highly skeptical that facebook has <i>anything</i> to do with this.<p>I would attribute it more to a standard cycle than anything else. Where I live, it used to be cheaper to get a house in the burbs...now it's cheaper to live downtown (factoring in transportation, food, etc). I also reject the assertion that suburbia is something from which we need to be saved - it certainly can be, but so can urban environments.
