Web 2.0

Web 2.0 is a trend in the use of World Wide Web technology and web design that aims to facilitate creativity, information sharing, and, most notably, collaboration among users. These concepts have led to the development and evolution of web-based communities and hosted services, such as social-networking sites, wikis, blogs, and folksonomies (the practice of catgorising content through tags). Although the term suggests a new version of the World Wide Web, it does not refer to an update to any technical specifications, but to changes in the ways software developers and end-users use the internet.

However, every blog you see and countless other websites can be defined as Web 2.0 sites. The technology is growing fast and certain websites are leading the charge. FaceBook, Wikipedia, Digg and YouTube are all providing popular services and are some of the biggest names in Web 2.0 development.

Reasons to go for Web 2.0 are:

• Data generation is almost free due to the fact that data originate from end-users

• Web2.0 is based on a self-service philosophy – users contribute what they know and find what they are looking for – on their own. This considerably reduces support overhead

• Lightweight business model

To sum up, web 2.0 is a technology that has brought a big change in the era of web technology and enlight people with a new web experience.
