The building of virtual communities and Web 2.0

Abstract

Web 2.0 is the term used to refer to the second era of internet and is highly marked by interaction and dynamism and by the contents generated by the users creating a great personalization. The Web 2.0 users change from passive agents to highly active agents who write, criticize and evaluate, and at the same time they are criticized and evaluated, generating a great exchange of information, creating, then, an enormous virtual communities network that shares knowledge and opinions. In the Web 2.0, whose key concepts are publication and participation, blogs, wikis, social and networking sites link much more people than information. Web 2.0 takes us to think in Pierre Lévy and Collective Intelligence (1998) that is a principle in which individual intelligences are pooled and shared by all society, being empowered by the information technologies as internet.
