This article at CNet takes a detailed look at the growth of social gaming through Apple's iPhone, a market many developers — and Apple themselves — are still struggling to figure out. The piece also speculates on how such games and networks will continue to evolve. Quoting: "While competition has spawned better features among these services, the future brings a growing need for a more unified network. Even if all these networks begin to become impossible to differentiate, users are eventually going to want a less-disjointed platform when jumping from game to game, and app to app. Thus far Facebook, and even Twitter to some degree have provided that constant, just by giving users a way to log in to these platforms. The unification can shake out in a number of ways though, the most likely of which is consolidation. Open Feint can continue to grow until it's snatched up by a larger company (like Apple). Or it can begin absorbing, or muscling out the other, less popular networks. As mentioned before, Apple plays a big part in this: not only in how it changes the hardware, but also how it continues to evolve the business of the App Store and information sharing between applications."
