What's missing in Web 2.0?

From Early Stage VC Peter Rip "I am not alone in observing where the world is going. The hard problems in the vision of a true web-as-platform involve all the usual hard computer science issues. How can we normalize information from disparate sources to make it interoperable? How do we get to a lingua franca without waiting for moribund standards (think CORBA and SOA)? How can we then manage the transition of legacy information and services into this world of interoperability?". THIS IS RIGHT ON!
