The "3.0" claim is ambitious, casting these new tools as successors to several earlier--but still viable--generations of Net technology. Web 1.0 refers to the first generation of the commercial Internet, dominated by content that was only marginally interactive. Web 2.0, characterized by features such as tagging, social networks, and user-created taxonomies of content called "folksonomies," added a new layer of interactivity, represented by sites such as Flickr, Del.icio.us, and Wikipedia.
Analysts, researchers, and pundits have subsequently argued over what, if anything, would deserve to be called "3.0." Definitions have ranged from widespread mobile broadband access to a Web full of on-demand software services. A much-read article in the New York Times last November clarified the debate, however. In it, John Markoff defined Web 3.0 as a set of technologies that offer efficient new ways to help computers organize and draw conclusions from online data, and that definition has since dominated discussions at conferences, on blogs, and among entrepreneurs.
