Web 2.0

Web 2.0 is a trend within the World Wide Web. It makes use of a variety of applications and applies them to the design of a website. It is a term popularised by O'Reilly Media.

The main difference between Web 1.0 and Web 2.0 is the amount of interactivity available to the users of the website. Majority of Web 1.0 sites were primarily information based.

Tim O’Reilly definition of Web 2.0:

“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. “
