The term "Web 2.0" refers to a perceived second generation of web development and design, that aims to facilitate communication, secure information sharing, interoperability, and collaboration on the World Wide Web. Web 2.0 concepts have led to the development and evolution of web-based communities, hosted services, and applications; such as social-networking sites, video-sharing sites, wikis, blogs, and folksonomie.
I’m often asked what is web 2.0 and the explanation I find easiest to give is that web 2.0 refers to web based platforms that have been developed to make sharing information, communicating and working together easier.
