Today Yahoo opened up their Digg-esque Buzz tool to allow links to any site. Previously, only about 400 publishers were included in the service (100 when it first launched). By allowing anyone to post to Buzz, Yahoo is possibly gaining better content, but also creating opportunities for gaming.
Digg has created a complex algorithm to attempt to combat spammers. The prize for making a link popular on Digg is a trip to its homepage, ensuring oodles of traffic for the linked site. Those that make it atop Buzz could find themselves with a real treat: a prime spot on the Yahoo home page. As Crocodile Dundee might say, “That’s not traffic, this is traffic.”
There’s no doubt, Yahoo is bringing Web 2.0 to the masses. The big question remaining is do they want it? Even though Digg has been doing this for years, it’s important to remember this is brand new territory for most of Yahoo’s user base. It’s still not clear if they’re comfortable “buzzing up.”
During the six months that Buzz was exclusive, Yahoo must have performed many tests to determine that its users wanted to participate. Prior releases would suggest the outcomes of these tests must have been positive.

One upside to Yahoo Buzz is that it’s so far not self-referential. If Digg had an announcement as big as this, you’d bet the home page would have Digg stories galore. That may just take time, the Up and Coming buzz shows a Buzz story is on the way.
As we mentioned when Buzz launched, it has some features that set it aside from Digg. There are a number of factors other than buzzing up that decide what makes it to the top of Buzz. Many of those metrics are Yahoo-specific, such as searches on Yahoo search and the number of times users email the page to friends.
I’m not convinced Yahoo Buzz will be successful as a destination, but the tool could be sprinkled throughout the other channels, similar to Yahoo Answers.
This news for publishers can only be positive. This is another way to get your content out there, and Yahoo’s audience of a half billion is a mighty number. In fact, why not buzz this post now?
[Full disclosure: Wired.com was one of the 100 publishers participating in the beta phase of Yahoo Buzz. Wired is also owned by Conde Nast, which operates Reddit, a potential competitor to Yahoo Buzz.]
