Since blogs, blogging, and RSS are popular topics of discussion for many people these days, including members of the search engine industry, the following "just released" report might be of interest to some of you.
+ 8 million American adults say they have created blogs
+ Blog readership jumped 58% in 2004 and now stands at 27% of internet users
+ 5% of internet users say they use RSS aggregators
+ 12% of internet users have posted comments or other material on blogs
+ 62% of internet users do not know what a blog is
Btw, some additional stats about RSS that might be of use.
In late October, Rich Skrenta posted that RSS usage is at about 12% at Topix.net. Rich also said in October that just 7% of the 7000 sources Topix was crawling at that time offered RSS feeds. A member of the Waypath team reported in the SEW Forums that 63% of the weblogs they crawl have feeds; just 22% have full-text feeds.
Thanks to S.C. for the news tip.
