Another brutal day for Facebook shares. The stock broke $18 for the first time, falling as low as $17.58.

It's been another controversial day for Facebook. Andrew Ross Sorkin at the New York Times wrote a column on Facebook's IPO blaming CFO David Ebersman for the stock's crash.

Sorkin says Ebersman priced the IPO too high which has led to the crash.

We don't blame Ebersman, he did what he was supposed to do. He got Facebook as much money as possible. If there's anyone to blame it's the investors who bought Facebook at $38 in the IPO.
