Compact Definition of Web 2.0

Web 2.0 is the network as a platform, spanning all connected devices; Web 2.0 applications are those that make the most of the essential 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.
