AP Story on Blogs
This says between 2 and 7 percent of adult Internet users in the US have blogs, with only 10 percent of those updating daily. My favorite factoid is that, "About 11% of Internet users report visiting blogs written by others. Most often, they were for blogs written by friends. But blog readers are more likely to go to journals kept by strangers rather than by family members." I wonder if that's because we don't really want to see the private musings of our family members (or don't know our family members even keep blogs, thank God).
