According to a study conducted by the Project for Excellence in Journalism only one percent of blog posts on any given day involved a blogger interviewing someone else and only five percent involved some other original work, such as examining documents. The study looked at a day in the life of the media on May 11, 2005 - a date picked randomly.
What I glean from this study is that the majority of bloggers generally amplify news through pointers and commentary to information others might not see. They're not conducting real thorough reporting. The data points really don't say that here, but it sure hints it. The report just says that bloggers haven't institutionalized some of the same practices that the pros have.
