Zuckerberg has accomplished quite a lot in 2010. He made sure that Facebook became the biggest social network, not to mention one of the most exciting Internet companies to work at. Facebook also managed pass the 500 million user mark this year, 200 million of which use the mobile version.
His company aside, Zuckerberg is also one of the world's youngest billionaires. He is also among 17 US billionaires that recently took the "Giving Pledge" to donate the majority of their wealth to charity, a project launched this year by the two richest Americans, Warren Buffett and Bill Gates.
