Close to 15 months ago, when The Social Network starring Jesse Eisenberg as Mark Zuckerberg released, the catch-line of the movie read as - "You don't get to 500 million friends without making a few enemies". Today, 15 months later Facebook has over 800 million users and has grown at a rate of 60% in the last five quarters with close to 75% of its users coming from outside the US. With Facebook set to go public in 2012 with a predicted valuation of $100 billion, Zuckerberg's retort to Bob doubting his ability to be the next Bill Gates will come unfounded as he will net a cool $24 billion post IPO.
