Turn in Facebook Valuation Meme?

Silly story reporting that Facebook has cooled because equity sellers failed to sell at a $90 billion valuation or a 80% increase (240% annualized return) in valuation only 4 months after the Goldman/DST investment at a $50 billion clip.  Dumb, at least with the facts stated in the story, but perhaps these are the story memes that make investor reexamine the Facebook thesis.  See prior posts – here, here, here and here.
