The four-year old social bookmarking site Digg offers a way and a platform for users to contribute, share news stories as well as items of interest with other like-minded users.

The most popular pieces get the most ‘Diggs’, and are highlighted on the front page. Digg now attracts every month almost 26 million unique visitors, with 3 million registered editorial personnel (those who submit, share, vote on, etc.).
Kevin Rose, the founder of the popular social bookmarking site, reveals the secret of the site’s popularity in an interview to The Guardian newspaper. He says,

People wish to have a voice and also a say in what is news.

It is about seeing what the masses actually want to surface, which articles they find the most interesting, and often they unearth and push stories to the front page, which you would not find anywhere else. These stories would get buried on a traditional news web site.

Is Digg his main source of news? He responds:

What gets me excited about visiting the front page is the distinct flavour of the community.
