"Mark Zuckerberg is the 52nd wealthiest person in the world, but he's not the only billionaire at Facebook. Six of the social network's founders and investors are among the richest people in the world. \nFacebook CEO and co-founder Zuckerberg has an estimated worth of $13.5 billion. In 2010, his worth was estimated at $4 billion and he was ranked 212th \u2014 quite an increase for the 26-year-old. \nBut that's not to say Zuckerberg's keeping the money all for himself. In the past year he donated $100 million to the Newark public school system, and he's committed much of his wealth to  charity. \nFacebook's other co-founders, Dustin Moskovitz and Eduardo Savarin, as well as investors Sean Parker and Yuri Milner joined the billionaire club during the past year too, according to Forbes's list, released Wednesday. \nMoskovitz, who is six days younger than Zuckerberg, is the youngest of all the billionaires, with an estimated net worth of $2.7 billion. Saverin, age 28, and Parker, age 31, are each worth $1.6 billion, according to Forbes. Milner, a 49-year-old Russian, is worth $1 billion. \nInvestor Peter Thiel made the list again this year, with a net worth of $1.5 billion.\nFacebook, along with its founders and investors, has seen incredible growth in the past year. The social network now claims more than 500 million members, and more than 42% of the U.S. population. It was recently valued at $65 billion, and earlier this year, Goldman Sachs and Russian investment firm Digital Sky Technologies invested $500 million in Facebook.\nIt's likely the Facebook executives and investors will only continue to grow in value, too, as the social network's products become more and more ubiquitous and integrated across the web  and mobile. \nForbes's list of the world's billionaires includes 1,210 people and more than 80 of them are from the technology industry. Bill Gates, of Microsoft, and Larry Ellison, of Oracle, represent the industry in the top 10 billionaires, with net worths of $56 billion and $39.5 billion respectively. \nHow long do you think it will take for Zuckerberg to be ranked among the likes of Gates and Ellison in the top-10 wealthiest people in the world?\nPhoto Courtesy of Flickr, deneyterrio"^^<http://www.w3.org/2001/XMLSchema#string>
