From Wikipedia: Web 2.0 generally refers to a second generation of services available on the World Wide Web that lets people collaborate and share information online. In contrast to the first generation, Web 2.0 gives users an experience closer to desktop applications than the traditional static Web pages. The term was popularized by O'Reilly Media and MediaLive International as the name for a series of web development conferences that started in October 2004. Web 2.0 applications often use a combination of techniques devised in the late 1990s, including public web service APIs (dating from 1998), Ajax (1998), and web syndication (1997). They often allow for mass publishing (web-based social software). The term may include blogs and wikis. To some extent Web 2.0 is a buzzword, incorporating whatever is newly popular on the Web (such as tags and podcasts), and its meaning is still in flux. O'Reilly recently claimed exclusive use of the term for conference names, further muddying the waters.

Well, it's the web that's after web 1.0... duh...

Rejected slogan #235: <a href="http://yedda.com" rel="nofollow">Yedda</a> - a brain the size of a planet.

ahhh...NOW it works.

I was wondering - is there a "very stupid answer" rank?

Web 2.0 is a term often applied to a perceived ongoing transition of the World Wide Web from a collection of websites to a full-fledged computing platform serving web applications to end users. Ultimately Web 2.0 services are expected to replace desktop computing applications for many purposes.

Love, respect & compassion is all it takes to create heaven on Earth.

another aspect of web 2, beside the ones already mentioned is that web 2 tries to enable cooperation between web sites and web service, that till now wasn't available.

it is doing so by creating tools for information sharing and marking.

best example of this tools is Tags - a key word, or words, that describe the data you have. if one site tells where it's tags are stored and what type of information they are marking (for example, bookmarks or pictures) other site can use this data and combine it with another (for example - place pictures on a map according to the place they were taken at).

 in the future, AKA web 3.0 or Semantic web, the computer it self will understand those tags according to their meaning (stories as in tales or as in a floor in a building) on its own, without the help of a human being.

The concept of "Web 2.0" began with a conference brainstorming session between O'Reilly and MediaLive International. Dale Dougherty, web pioneer and O'Reilly VP, noted that far from having "crashed", the web was more important than ever, with exciting new applications and sites popping up with surprising regularity. What's more, the companies that had survived the collapse seemed to have some things in common. Could it be that the dot-com collapse marked some kind of turning point for the web, such that a call to action such as "Web 2.0" might make sense? We agreed that it did, and so the Web 2.0 Conference was born.
