Web 2.0 commonly refers to the second generation of web development and usage.
Rather than the web being simply a tool to provide information to the user, or to sell products and services online, Web 2.0 uses the web as a collaborative and participatory tool in itself.
The growth in social networking sites such as Facebook, Bebo and MySpace; the explosion of user-generated (and user-managed) websites such as Wikipedia; and the upsurge in niche and vertical sites rather than broad content sites; are all part of Web 2.0.
