WEB 2.0 refers to websites that emphasize user-generated content, ease of use, participatory culture and interoperability. Examples of WEB 2.0 tools include wikis, which allow collaborative editing of web pages, RSS feeds for sharing updates, weblogs, podcasts, videos, photo sharing sites, social bookmarking, personal learning environments and online office suites. While WEB 1.0 focused on static websites created by developers, WEB 2.0 facilitates sharing and interaction between users.
