2011 is the year Facebook growth (users, hours, page views, pick one) plateaus, it is inevitable it will happen as some point, and this is very likely the year.
we shouldn't, really. I mean, they practically /made/ the bubble, and I think we've all profited from that, even those of us who don't work for google. Demand for webapp dudes (and infrastructure) is way up because of this bubble. Hell, my own biggest account does some kind of facebook app thing.
