Talking about Web 2.0, this only represents the improvement or total changes in the internet since Web 1.0. A feature of Web 2.0, which seems discriminating is the rate of change in information. Mostly in Web 1.0, the displayed information on the screen is static, and the updating of data is not needed to be done frequently. About Web 2.0, the rate at with information is updated quite fast, and the information is so dynamic. Two good examples of the way Web 2.0 is, are technologies like syndication, and sites like Twitter.
Another significant difference between these two is the rigidity structure in the flow of information when it comes to Web 1.0, where the information to be put up is determined by webmasters, and are later downloaded or viewed by the end users. The control over content is accessible by the end users in Web 2.0. Some examples of how Web 2.0 is are social sites like Myspace, Facebook, Orkut, and some others.
