Yahoo in the news ranking business

Just got an email about Yahoo! Buzz, a new service designed to compete with the likes of Digg and Reddit. It's still in beta, but from the looks of it, users vote on the popularity of news items (including blog items) and the news gets ranked accordingly.

Interestingly enough, many of the rankings list Yahoo News as the source, even though Yahoo aggregated the news from some place else, likely a wire service. That only seems to add confusion to the whole did-this-come-from-a-credible-source conundrum of internet journalism.
