Jeff Jarvis summarizes some amazing stats on the growth of blogs, from the latest Pew Internet and American Life study:

* 7% of the 120 million U.S. adults who use the internet say they have created a blog or web-based diary. That represents more than 8 million people.

* 27% of internet users say they read blogs, a 58% jump from the 17% who told us they were blog readers in February. This means that by the end of 2004 32 million Americans were blog readers.

The same study reports only 38% of all internet users know what a blog is. The rest are not sure what the term blog means. That 62% is in daily contact with me.
