Understanding Web 2.0: Techniques, Innovations, and User Participation

Web 2.0 marks a significant evolution of the Internet, focusing on user-generated content, interactivity, and collaboration. Key features include Rich Internet Applications, AJAX, semantic XHTML, RSS/Atom data syndication, and folksonomies like tagging. This transformation encourages participation, allowing users to act as co-developers. From blogging and wikis to mashups and REST APIs, Web 2.0 changes how we engage online, shifting from static pages to dynamic platforms. The rise of social media and collaborative tools has redefined web experiences and operations.
