Web 2.0 refers to second-generation web-based communities and services that facilitate user collaboration and sharing. Key aspects include social media sites, wikis, folksonomies, and harnessing collective intelligence. Web 2.0 represents a shift from static web pages to dynamic applications that use technologies like AJAX and APIs. It emphasizes openness, participation, and lightweight business models enabled by content syndication.

Concise Web 2.0 Explanation http://web2journal.com/read/165914.htm “Web 2.0 is the network as platform, spanning all connected devices; Web 2.0 applications are those that make the most of the intrinsic advantages of that platform: delivering software as a continually-updated service that gets better the more people use it, consuming and remixing data from multiple sources, including individual users, while providing their own data and services in a form that allows remixing by others, creating network effects through an “architecture of participation,” and going beyond the page metaphor of Web 1.0 to deliver rich user experiences.”
