Facebook really is That company. Which company? That one. That company that shows up once in a very long while—the Google of yesterday, the Microsoft of long ago. That company where large numbers of stunningly brilliant people congregate and feed off each other’s genius. That company that’s doing with 60 engineers what teams of 600 can’t pull off. That company that’s on the cusp of Changing The World, that’s still small enough where each employee has a huge impact on the organization…That company where everyone seems to be having the time of their life.
