There is growing debate as to whether Web 2.0 will prove to be a bubble. Many warn the growing industry could suddenly collapse, just as the dot com bubble burst in 2000 and 2001. Web 2.0 refers to web services that allow users to freely participate in the production and distribution of information, taking full advantage of the interactive properties of the Internet. Several major Internet companies that survived the first bubble like Amazon, eBay and Google have something in common: they pro-actively embraced the concepts of Web. 2.0.
