Developer Digital Chocolate (who, according to that recent slideshow report, is one of the most frequent publishers of content to the App Store) has announced that they'll be going with OpenFeint for their social networking features. We've been covering OpenFeint for a while here on TUAW (and we've interviewed them before as well). The platform is designed to let devs add social features and multiplayer to their apps quickly and easily. And that's exactly what Digital Chocolate will be doing with it, apparently -- they'll be putting scoreboards and achievements into their games on the App Store.
This hardly means the end of the ongoing battle over social networking and app developers on the store. But platforms like OpenFeint, Plus+, and others continue to stack up developers under their respective umbrellas, and it remains to be seen just who will prevail.
