Mark Zuckerberg Is Now One of the Poorest Billionaires in the US, Says Forbes

This time last year, Mark Zuckerberg, founder and CEO of Facebook, was one of the richest people in the world rapidly climbing through the rankings. With the IPO coming and Facebook's valuation reaching new heights, it couldn't have been a sweeter time.

How much of a difference a year can make. Today, Mark Zuckerberg is still one of the richest people in the world and can still afford to buy and wear a new grey t-shirt and a Facebook hoodie each day for the rest of his life and probably several times over.

But he plummeted from being the 14th richest billionaire in the US to being the 36th. Bill Gates is probably already finding it embarrassing to hang out with him.

Don't feel too bad for poor old Zuck, while times are harder, he's still worth some $9.4 billion, €7.2 billion though he did lose $8.1 billion, €6.2 in just one year.
