From Wikipedia: Web 2.0 refers to websites that emphasize user-generated content, usability (ease of use, even by non-experts), and interoperability. Examples of Web 2.0 features include social networking and social media sites (e.g., Facebook), blogs, wikis, folksonomies (tagging), video sharing sites (e.g., YouTube), hosted services, Web applications (apps), collaborative consumption platforms, and mashups.
The term Web 2.0 is no longer in active use, and Web 3.0 has been used to refer to the semantic web. Here are technologies and techniques associated with three waves — not only for the web, but also for knowledge management (KM).
