Yahoo Buzz

Users can be allowed to publish their own news stories, and link to their own or another person's site that links to a full story of the information, therefore driving traffic to that person's website and creating a larger market for sites that research and publish their own news articles and stories, such as CNN or smaller, privately owned websites.
Buzz, also like Digg, promotes the news stories that have been the most buzzed by users and displays them to the visitors of the website on the main page.
Buzz was created as a direct competitor to Digg.
