Technorati has been tracking the blogosphere through its State of the Blogosphere study since 2004.
The goal of the study is to create a complete snapshot of the activities and interactions that make up the Blogosphere by asking you, the bloggers, to share some information about your habits. The survey includes questions like how, when and why you blog. Is this a side business, full time job or something you do for fun?
It took about 15 mintues to complete.
Results will be published on its website on November 3.
