If Mark Zuckerberg had stayed in school, he'd be a recent grad, maybe settling into a new job or place to live, or continuing to search for that first big break. But as daunting and uncertain as those first few months may have been, they'd be a breeze compared to what Zuckerberg faces now.
The 22-year-old is founder and chief executive of Facebook.com, the social-networking site of choice for college students and the seventh most trafficked. Despite scant experience, Zuckerberg runs a 150-person company that has raised $38 million in venture capital. He turned down at least one acquisition offer for $750 million, and recently signed an advertising deal with Microsoft (MSFT) that those close to the company say is worth hundreds of millions of dollars over several years.
