The revolutionary developments in IT (Information and Technology) sector and the increasing use of the Internet has changed our lives irrevocably and for the better. More and more people today are using this medium to connect, communicate, assess information, and be in the know of things.

Most of us are glued to the Internet – in our homes as well as work areas – and are spending a considerable part of our time surfing the Internet. However, there remains some doubt as to whether we are aware of the true power of this medium.

The utility value of the Internet is being recognised at various levels and the concept of active participation over the web is being streamlined to suit myriad needs. Web 2.0 sites act as platform and enable interaction amongst the people visiting these sites. People can express their views and opinions on different topics; their experiences, anecdotes, and shared knowledge can create some very informative content for the web. The best part about the web 2.0 sites is that the content is not boring and monotonous; on the contrary the content is informal and scores high over what is there in other sites.

The web 2.0 sites play a vital role in social networking and can go a long way to eliminate cultural and regional barriers. Visitors to these sites can interact across communities and discuss the common issues that are effecting them. The subject of discussion can be as varied as the next football world cup to the latest developments on the political front in any particular region.

The best part about these web sites is that they can be used for developing businesses as well. Business owners can use the web 2.0 sites to promote their products and services and hope to accrue significant profits. At the present moment, there is a lot of awareness about these networking sites. More and more people are opening up to this idea of web 2.0 sites and using them to make the most of all their online activities and endeavours.
