Definition
Web 2.0 is one of those "buzz words" like DHTML that do not have a clear meaning but does refer to a trend or practise that does favor new technologies.
According to Tim O'Reilly (2005), Web 2.0 can be defined through examples of how typical web services did evolve. E.g.
</tbody> What is common about these example is that “behind the success of the giants born in the Web 1.0 era who have survived to lead the Web 2.0 era appears to be this, that they have embraced the power of the web to harness collective intelligence” (O'Reilly, 2005), in other words Web 2.0 is strongly related to social computing and collective intelligence (the "wisdom of the crowd"). A few years ago, there was a lot of talk about the semantic web. This didn't happen so far ;). So more and more it appears that Web 2.0 means actually going back to the roots of academic Internet in the 80' and very early 90' which was all about communication and exchange.References
