It's official, Yahoo's Digg-style Buzz is now open to all publishers. Unlike Digg, one of the main features of Buzz is to push content to the home Yahoo page - a chance for publishers to gain a monumental amount of attention and traffic. In addition, Buzz's algorithms take into account search engine popularity (so it takes a little more than voters gaming the system) and there's a push to feed Buzz stories into users' personalized Yahoo (my.yahoo.com) pages - another good source of significant attention. Through Buzz, after submitting you will also be able to share content through Delicious, Digg, StumbleUpon, Reddit, Facebook and Propeller.

Simply put, Buzz cannot be ignored. Publishers have a big opportunity to hit an enormous audience - far, far beyond Digg or any other single bookmarking service. Like anything else, the earlier you start, the better.
