A lot of people think Facebook's $15 billion valuation is kind of insane, given that dick-ish founder Mark Zuckerberg hasn't really figured out a way to make any real money. Not a good sign for a company that is trying to go public sometime in the near future! Which may be why some employees are already trying to furtively offload stock at way below the valued price.
TechCrunch's Michael Arrington got his hands on an e-mail from a high-end money manager named Bill Dagley in California, in which Dagley is testing the waters to see if anyone is interested in "buying shares of Facebook from current holder." A person approached by Dagley tells Arrington that the asking price was $3 to $4 billion. Arrington also floats the rumor that Zuckerberg himself has explored selling some stock at a $6 billion valuation, though he's unable to confirm this.
