Facebook Executives Leave as the Company Grows

In the last few days co-founder Josh Williams and the head of U.S. sales have announced that they are leaving

Facebook executives and senior staffers have been saying goodbye to the social network at a speedy rate ever since its May 2012 initial public offering.

In the past few days alone, head U.S. sales guy Tom Arrix and Gowalla co-founder Josh Williams have said they're headed for the exits. Sure, Facebook, with 4,900 employees, should be forgiven for some expected turnover, but when the top brass bow out in successive fashion, some without rhyme or reason, you can safely bet that it's not all sunshine and rainbows inside the world's largest social network.
