From there, just like on Digg’s strikingly similarly named “Upcoming” section, you can filter by “most recent” or “most votes.” You can also drill down into specific categories like Entertainment or Politics to see emerging stories in topics of interest. Of course, the big deal with Buzz is that if a post gets enough momentum, it can end up on the Yahoo homepage, in turn sending a ton of traffic to the publisher.
In short, adding an “Up & Coming” section shows off more content to Buzz users, hence, increasing the odds of a story making it all the way to the most traffic webpage in the world. Given Yahoo’s extremely large and diverse userbase, it also may provide a better representation than Digg and other social news site of what stories are actually gaining mindshare on the Web.
