The companies that are doing actually interesting things are using technology to make non-tech stuff easier/better/faster/brighter: Uber, AirBnB, Zipcar, that female-led startup connecting farmers with buyers, etc.
Technology for technology's sake is done and boring and short-sighted. We've got news aggregators that aggregate other news aggregators. Mobile ad platforms that resell ads from other mobile ad platforms. Photo-sharing apps whose entire purpose is to create filters for other photo-sharing sites. And it's all ad-supported.
Arrington's right: it's all just the same thing over and over, and it's boring. And I never thought I'd agree with Arrington about anything.
