Yahoo! Buzz is a community-based news article Web site, much like Digg, that combines the features of social bookmarking and syndication through a user interface that allows editorial control.
Users may 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 Web site and creating a larger market for sites that research and publish their own news articles and stories, such as CNN or smaller, privately owned Web sites. And, unlike other social networking sites, Buzz allows the publisher to modify the submission.
Yahoo Buzz also publishes the hottest stories from a broad assortment of Web publishers throughout the day, and gives users a chance vote ("buzz") stories up or down, submit them to Buzz in the first place, and comment on them.
