Like many other social content websites (e.g. del.icio.us, Digg, Propeller, Reddit, and StumbleUpon), Yahoo! Buzz allows people to express a like (or dislike) for articles, videos, photos, and other content. Yahoo! Buzz is unique, however, because our rankings also take into account things like trends in search queries on Yahoo! Search, and the number of times that content is shared with friends over email.
Please note that in addition to consuming and interacting with content on Yahoo! Buzz, you can also submit content you find on Yahoo! Buzz to many of the top social content websites, directly from the Yahoo! Buzz website itself. Click on the “Share” button under each story or video on Yahoo! Buzz to do so.
