We should however be realistic: the 'blogging revolution' collided with human nature and human nature won. Most people do not like writing, even if they have something to write about. Many people do not have time to blog on an ongoing basis in a way that attracts a substantial audience.
While I agree with this statement in blog statistics and demographis in the profile from Caslon Analytics on blogging, I agreed with it in 2001. So I guess this statement is so, so yesterday? Even using the amazingly simple technology of pen and paper, not a lot of people write. For those who do, who enjoy writing and enjoy communicating online, weblogs will, in some form, continue to be part of their toolbox. But it will still be possible to survive without a blog.
