INTERNET 2.0

Web 2.0 is the network as platform, spanning all connected devices; Web 2.0 applications are those that make the most of the intrinsic advantages of that platform: delivering software as a continually-updated service that gets better the more people use it, consuming and remixing data from multiple sources.The Web, though, is becoming the first piece of the bigger network as it meshes with new technologies that started from disparate corners of the industry — such as Wi-Fi wireless broadband connections, the Global Positioning System (GPS) and radio frequency identification tags (RFID).Web creator Tim Berners-Lee has been talking about a version of such a system for a couple of years. "The Web can reach its full potential only if it becomes a place where data can be shared and processed by automated tools as well as by people,".

In the year and a half since, the term "Web 2.0" has clearly taken hold, with more than 9.5 million citations in Google. But there's still a huge amount of disagreement about just what Web 2.0 means, with some people decrying it as a meaningless marketing buzzword, and others accepting it as the new conventional wisdom.
