Facebook founder is now richer than Apple CEO

According to the latest Forbes 400 rankings, The founder of Facebook, CEO Mark Zuckerberg is now richer than Apple CEO Steve Jobs. This year, Zuckerberg, 26, added $4.9 billion to his fortune – vaulting to #35 on the Forbes 400 with an estimated fortune of $6.9 billion.
Why the jump? Recent private equity investments in Facebook valued the firm at around $23 billion – more than triple its 2009 value of $7 billion.
