According to a study conducted by the Project for Excellence
in Journalism (May 11, 2005) 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.
Bloggers generally amplify news through pointers and commentary
to information others might not see.
They're not conducting real thorough reporting and haven't
institutionalized some of the same practices that the pros have.
