56% of Active English Blogs are Spam -- Wired

An article on splogs in Wired's Sept '06 issue quotes Timm Finin, a researcher at the University of Maryland, Baltimore County, and two of his students as saying 56% of active English blogs are spam. "The Blogosphere is growing fast," but "the Splogosphere is now growing faster."

The article goes on to say that splogs contribute about 75% of all pings from English-language blogs. About 300,000 legit posts a day and about 900,000 bogus ones.
