Keyboards were clicking this week as bloggers both hailed and blasted the results of a comScore's blog-user study (PDF), "Behaviors of the Blogosphere," issued this week, with the two best-known blog networks squaring off and trading accusations, writes ClickZ. The study was cosponsored by Six Apart and publisher Nick Denton's Gawker Media blog network, which was accused of bias by rival Weblogs Inc. Network (WIN) publisher Jason Calacanis.

Media buyers have long sought the demographic data that the study offers, and all major blog publishers will likely benefit from findings that blog audiences tend to be wealthier and younger than the average web audience. But Calacanis accused comScore of bias and inconsistency.

Pointing to discrepancies between blog traffic rankings in the report and those sites' own stats, Calacanis is particularly upset at the report's ranking of Gawker.com above WIN's Engadget.com, according to ClickZ. He has also accused comScore of bias based on the personal relationship between Denton and the report's coauthor, Rick Bruner, who is also director of research at DoubleClick. Denton and Bruner are friends.

Bruner said he approached comScore to produce the report, ComScore agreed but wanted a sponsor, so "I reached out to Nick and the folks at Six Apart, they were interested and we got the sponsorship and proceeded."

Denton dismissed Calacanis' objections. "I know it galls Jason Calacanis that his sites are about as memorable as Burger King franchises, and that none register among the top blogs, except Pete Rojas's Engadget," he said.
