Designing for the web, today requires leveraging knowledge and well-tested design principles while escalating the amount of interaction and "social" components accessible to your users.
The Web 2.0 has apparently brought major design innovation in the form of rounded corners, pastel colors, 3D embossed shiny buttons, floor reflections and large text captions and many, a designer have quickly adopted and made theirs this new simpler, more visually impactful and highly intelligible 2.0 technique
If Web 1.0 is about static pages and retrieving information, Web 2.0 is about dynamic pages and sharing information. Widespread computer illiteracy and slow internet connections added to the restrictions of the internet, which characterized Web 1.0. The shift from Web 1.0 to Web 2.0 is a direct result of the change in behavior of those who use the World Wide Web.
While a Web 1.0 site mainly contains 'read-only' material, a Web 2.0 website allows its users to interact with other users or to change website content, in contrast to non-interactive websites where users are limited to the passive viewing of information supplied to them.
Rich user experience, user participation, dynamic content, metadata, web standards and scalability are some of the features of Web 2.0 Designing. Some of the key Web 2.0 website development include:

Social Networking sites

Wikis, Blogs and Micro blogs
