what is web 2.0

the term Web 2.0 does not have an exact definition. It was first coined by publishing group O’Reilly Media in 2004 at a brainstorming conference intended to look forward to web developments arising from the ashes of the dot-com collapse in 2001.An O’Reilly paper on the matter suggested that Web 2.0 be visualized “as a set of principles and practices that tie together a veritable solar system of sites that demonstrate some or all of those principles.Put another way, Web 2.0 envisaged “the web” as a platform for the delivery of services, with web browsers and web servers being little more than commodities. As the O’Reilly conference perceived it, the real value would lie in the services.
