Facebook's fall has been steeper and faster than even the harshest critics predicted when it went public in May.
The social network's stock is down nearly 5% today, sinking to a new low under $20.
The company just revealed that 9% of its users' accounts are fake. And to make matters worse, Mark Zuckerberg's senior executive team is thinning out. Katie Mitic and Ethan Beard both announced they are leaving Facebook. Ethan, who was the company's director of platform partnerships, is leaving "to start a new venture."
