Zynga may be a newcomer to the market in 2012, but Pincus is well on his way to becoming a lifetime member of the gaffes list following his dump of 16 million shares of his personal stock just weeks before Zynga's quarterly report "farmed" about half of the market value out of Zynga's stock. Things have gotten even worse since that report, with Zynga and Facebook restructuring their relationship, and with the amount of paying users falling despite an increase in unique game users. Perhaps the defining moment of Pincus' year, outside of the insider trading allegations, or its ridiculously overvalued purchase of OMGPOP, which has already been written down significantly, is the mass exodus of executives from Zynga to literally anywhere not named Zynga. In total, Zynga has now lost 10-plus high-level executives. 1. Sean Menke, former CEO of Pinnacle Airlines And the winner of all losers is... Sean Menke of the now-bankrupt Pinnacle Airlines!
