Zynga's big collapse: Is the social gaming fun over?

The company behind Farmville, Words With Friends and other games distributed mostly via Facebook reported a second quarter net loss of $22.8 million, or 3 cents a share, on revenue of $332.5 million.

Zynga CEO Mark Pincus said that the company faced "new short-term challenges," but was "optimistic about the long-term growth prospects on mobile." Pincus noted that Zynga has a window of opportunity to drive the social gaming revolution.
