Facebook fever

Bill Gates had better watch his back.
With Facebook’s frenzied IPO headed toward a huge first-day pop, Mark Zuckerberg, already the world’s youngest paper billionaire, is poised to shoot up the list of the wealthiest people and could catapult past the ranks of well-known, and much older, heavyweights — even fabled investor Warren Buffett.
At the high end, Zuckerberg’s cut of Facebook is worth $19.25 billion after the company raised the price for its initial public offering to a $34 to $38 range. His personal fortune, however, could more than double if Facebook’s shares explode in their first day of trading, similar to LinkedIn’s spectacular debut.
