Web 2.0 is the fashion, the trend, the purpose.

On web 2.0, we cannot only get but also deliver data; cannot only benefit from, but also contribute to the websites content; cannot only be a visitor, but also an online editor.

Web 2.0 applications do not only display information but also input data from users; they usually may be run directly through a browser by the means of interactive friendly consoles.

Web 2.0 will soon become the platform of all local networks, and personal computers will be end-user terminals of the web 2.0 internet.
