Doesn't seem like he's calling Facebook a fraud. But Enron had a famously superstar-driven culture. In particular, they had a fairly strict employee ranking system. Every year, each employee would be assigned a quintile based on performance. The top 20% of performers would always get raises, and the bottom 20% would always get fired. Sounds like a great system in theory, but from what I hear from people who were there, it led to a poisonous and cutthroat culture. Not sure if the same will happen to Facebook, but there certainly are some dangers.
