From its inception as a global hypertext system, the Web has evolved into a universal platform for deploying loosely coupled distributed applications. As we move toward the next-generation Web platform, the bulk of user data and applications will reside in the network cloud. Ubiquitous access results from interaction delivered as Web pages augmented by JavaScript to create highly reactive user interfaces. This point in the evolution of the Web is often called Web 2.0. In predicting what comes after Web 2.0--what I call 2^W, a Web that encompasses all Web-addressable information--I go back to the architectural foundations of the Web, analyze the move to Web 2.0, and look forward to what might follow.
