Digg is part of the social networking revolution. Part of a new internet that focuses on empowering the masses rather than a select few. It is the masses who get to determine what is valuable and what's note. Part of this revolution includes an overhaul in the way news sites work. The largest competitor to traditional news sources is Digg. Digg gives every reader the right to determine whether a story is worthwhile or not - and to submit stories from a multitude of sources.
No one reader has the power to make a story frontpage - but en masse, the users can determine what they want to read. Digg started as a strictly technology news site but has since expanded to include World and Business, Sports, and Entertainment. The technology news continues to include Technology, Science, and Gaming.
If you want to follow what is happening in the world, Digg is a great place to go. Articles are organized by category and include brief summaries that allow you to read through dozens of overviews in minutes and only go into depth on the articles you really want to know about.
