Web 2.0 is the network as platform, spanning all connected devices; Web 2.0 applications are those that make the most of the intrinsic advantages of that platform: delivering software as a continually-updated service that gets better the more people use it, consuming and remixing data from multiple sources, including individual users, while providing their own data and services in a form that allows remixing by others, creating network effects through an "architecture of participation," and going beyond the page metaphor of Web 1.0 to deliver rich user experiences.

"...the lack of a crisp definition is a feature, not a bug. And as the world shifts from the limited variety of bottlenecked distribution to the infinite variety of open distribution, there will be more examples of phenomena that are hard to define but are nevertheless real and true. The future is increasingly heterogeneous, not homogeneous.One size doesn't fit all."
Chris Anderson, “Web 2.0 and the Long Tail, Part 2”The Long Tail
