Web 2.0

The second generation of World Wide Web culture and technology. A Web 2.0 website is a medium for collaboration, sharing and participation, rather than one-way communication from website owner to website visitor.

Blogs and wikis are examples of Web 2.0 websites.

Web 2.0 and related terms such as Enterprise 2.0 and social media are widely discussed on the Web.
