9. Zynga's executive-retention program

9. Zynga's executive-retention program

All is not well on the virtual farm. There have been layoffs, a collapsing stock price, and just about everything that could go wrong at a young company after it's gone public.

But perhaps the most shocking development at the San Francisco maker of FarmVille and other games is the volume of executives heading out the door. Since August, the chief revenue officer, chief infrastructure officer, chief operating officer, and chief creative officer have all left the company, along with the treasurer, and general managers of CityVille and Mafia Wars 2. This, we assure you, is only a partial list.

It shouldn't be a surprise that Zynga's share price has dropped more than 75 percent since it went public last December. The good news for the executives leaving Zynga is they appear to be heading to greener pastures at companies like Facebook and Twitter. The bad news for the rank-and-file is there doesn't seem to be much reason to hope for a turnaround.
