A couple of years ago, the
people who are continually stretching the edge of the Internet
envelope began talking about Web 2.0. Wikipedia, the user-created
encyclopedia, defines Web 2.0 as "a term often applied to a
perceived ongoing transition of the World Wide Web from a collection
of Web sites 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."
