What is Yahoo Buzz?:
The Web’s most remarkable stories, determined by people like you. Stories are ranked based on your votes, emails, and searches.
Yahoo Buzz is yahoo’s new social bookmarking sort of website. Where popular articles are voted on, and publishers can get loads of burst traffic. Unfortunately the traffic possibilities of Yahoo Buzz are very similar to that off Digg. You must be on the front page to get a lot of hits, and the flow of traffic is cut short once your article leaves the front. Fortunately if you wrote a good post people would be bookmarking your blog and coming back to it later. Also, if you continue to write good posts you could be on the front page of yahoo buzz for quite a while.
The problem with yahoo buzz, is that smaller blogs don’t really have a chance to get their articles popular. Users can either vote for an article directly from the blog the article came from, or they can find the article on yahoo buzz and vote for it there. Usually this would mean that the smaller blogs would never get any of the traffic, but their is a possibility that a great article could be spotted and made popular.
Yahoo Buzz pulls in content from publisher partners across the Web.
You must be a partner with Yahoo Buzz in order to get your content pulled, but they don’t accept everybody. In fact, I gave them my email adress hoping to be invited to join, but I haven’t been yet. Maybe I won’t, do too… crappy blog posts? 
Yahoo buzz also has a widget, you can put on the side of your blog. The widget contains all of the most popular articles, so users reading your blog can click some link and go to a different blog with the popular post on it. Not exactly something I would use on one of my blogs, but it’s nice if your article is currently featured on the widget.
