The web 2.0 seems to be one of the most recent innovation on the Internet

Web 2.0, a phrase coined by O'Reilly Media in 2004, refers to a supposed second-generation of Internet-based services — such as social networking sites, wikis, communication tools, and folksonomies — that let people collaborate and share information online in previously unavailable ways. O'Reilly Media, in collaboration with MediaLive International, used the phrase as a title for a series of conferences and since then it has become a popular (though ill-defined and often criticized) buzzword amongst certain technical and marketing communities.

This new version of the web is hard to define without using technical explanations. That is why I would say Web 2.0 is simply a network based on relations between human beings more than a simple interface between the user and a machine. Web 2.0 includes XML (Extended Mark up Language), a language which bring interactivity to the foreground.
