Forbes magazine is out with its annual list of the 400 richest Americans, and while the names at the top are the same, there is one 26-year-old crawling his way there -- one Friend at a time.
For the 17th year in a row, Bill Gates sits atop the list with a net worth of $54 billion, up $4 billion from last year. He would be worth plenty more, but Gates is busy giving away his fortune to charity. So far he has given $28 billion to his foundation. (Wonder if he knows the Opposing Views School for Orphans with Malaria is now accepting donations?)
Gates' pal Warren Buffett is number two, at $45 billion. Buffett is another charitable man, urging his fellow billionaires to pledge at least half of their fortunes to charity.
The rest of the top ten has the usual suspects -- the family of the late Sam Walton, who founded Wal-Mart, Oracle's Larry Ellison, New York City Mayor Mike Bloomberg, but the man who sits at number 35 is the most surprising -- Mark Zuckerberg.
The Facebook founder, who is the subject of a critically acclaimed film currently in theaters, tripled his net worth to $6.9 billion, after the wildly popular Web site was valued at $23 billion. And that's considered a conservative estimate. That vaulted Zuckerberg past such stalwarts as Apple's Steve Jobs and News Corp's Rupert Murdoch.
Facebook's two little known co-founders, Eduardo Saverin and Dustin Moskovitz, make their first appearances on the list. Moskovitz is now the youngest billionaire in the world -- eight days younger than Zuckerberg. He's worth $1.4 billion, placing him 290th on the list.
