The iPhone and the Fat Head of Mobile Content

I continue to be impressed by the way in which the iPhone is tackling the “fat head” (as opposed to the “long tail”) of web content. For a phone with fewer than 1 million units as its installed base, the iPhone has done a remarkable job in doing something that few, if any, other mobile devices have been able to accomplish – convincing website owners to build specific instances of their websites optimized for their particular device. Seeing the great apps from Facebook, Netvibes, and Meebo is a pretty strong bet on the future of that platform.

If the iPhone has been able to do it, I wonder why the Treo and Blackberry haven’t had similar levels of success. And do you think it’s rationale for app developers to be building iPhone-specific applications?
