Web 2.0

Web 2.0 refers to a Web environment on the Internet that enables and supports user-contributed and managed content. The leading examples of this dynamic would be Ebay, Digg, and Wikipedia.

Critics such as Andrew Keen have taken a pessimistic view of Web 2.0, saying:

[The] Web 2.0 movement, [fuses] '60s radicalism with the utopian eschatology of digital technology. The ideological outcome may be trouble for all of us.

Actually, the site MyWikiBiz is a child of the Web 2.0 movement, but can also be considered a Web 3.0 experiment.
