Zynga is said to be moving games into the mobile market, but you also have to figure that being a gaming company is hard. You're top-rated game will be supplanted by something else in short order and you have to constantly be updating.
I think that the way Zynga acquired its customers/users is exacerbating the situation. If your friends are all there you feel compelled to join too, but if some leave it's socially acceptable to follow them elsewhere.
Since we're talking about "social" gaming, I also have to wonder whether part of the drop isn't seasonal ... at least where I live, it's now nice enough to spend a lot of time outside socializing (picnics, frisbee, t-ball, etc) so perhaps there's just not the boredom to drive as much traffic?
