While I don’t doubt Arrington’s prediction of Facebook’s deep, deep integration into the web for the foreseeable future, I’m not so sure the next decade will be known as the Age of Facebook so much as the golden age of the Apple Empire. There are other media players actually challenging Facebook (Google still sells a few ads, and has a few new developments that promise to extend that for some time, Twitter does pose a challenge on some real-time and location-based advertising fronts); there’s nobody that can touch Apple in mobile right now.  Until someone closes that gap, Jobs & Co. are getting one massive headstart on the digital channel that will define the next decade.
