Zynga (ZNGA -3.9%) is giving back some of the gains it saw on account of Mark Zuckerberg's talk. In addition to the recent avalanche of defections, concerns about the early uptake for FarmVille 2 (previous) have been weighing on investors. AppData claims the game's daily and monthly active users are still only at 300K and 680K, respectively. Jefferies recently argued anything less than 5M daily users would be disappointing, and that 20M would be needed for FarmVille 2 to be considered a "home run."
