Defining Web 3.0
The Web 2.0 vs Web 3.0 comparison is not something that can be easily defined given Web 3.0’s lack of a specific definition.
If Web 2.0 can be defined as a period of technological enhancement to static HTML generated web pages, offering the social networking, blogging and ecommerce tools that we take for granted on a daily basis, then Web 3.0 is something quite different; something to which comparison might be difficult.
Arguments as to what the definition of Web 3.0 might be range from the general term “semantic web" in which search is quicker and more comprehensive, thanks to a range of indexing systems such as tagging, to it being the time when the web and TV collide, to a disturbing definition of humans being constantly “plugged in" to the net.
The most simplest comparison then might be to understand Web 2.0 as a successful integration of many online services into use web-based mashups and apps, and Web 3.0 as the real world implementation of these services, best demonstrated with the use of the Layar system. Layar is effectively an invasion of 2D, online search services into 3D space with the help of camera mounted mobile phones, and presents information, clearly and relatively – an application of the semantic web. Our review of the Layar Reality Browser should make this particular Web 3.0 definition - probably the most popular - much clearer.
