Answer #1: The Pew Internet and American Life Project did a study in November which found that "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 or XML readers to get the news and other information delivered from blogs and content-rich Web sites as it is posted online; and 12% of internet users have posted comments or other material on blogs.
So the real question is, why did we only just get here?
Answer #2: Years ago and in a different community, Issan Dorsey used to tell us an old Napa State Mental Hospital joke. Someone asks, "Why are we here?" And everyone in the room shouts in chorus, "Because we're not all there!!" Considering how much undone work we at SFPL have at any given moment, we are certainly not-all-there if we are launching a blog!!
