The Facebook manual, to which all execs and investors now faithfully adhere, states that the social network will remain independent. Mark Zuckerberg's company won't sell to Yahoo; hell, they'll buy Yahoo one of these days. But, as recently as six months ago, some of the 23-year-old founder's key managers weren't so much on message. To one outsider who suggested they sell, one of the grown-ups answered: "Obviously, we all want to sell, at least some of the equity. But Mark owns the whole thing and he's a crazy kid. He doesn't let us in on his ideas, and all he cares about are the users." The users? Shocking.
