You can [now] get a free WordPress.com blog. I've had an account for a while now and the service is getting very slick.
The two-year-old WordPress software, which until now required installation by web developers, competes with other publishing platforms such as Drupal and Six Apart's Movable Type. It is downloaded 4,100 times per day, and runs content management for the CNET portal and tech blogger/journalist Om Malik, among many others. WordPress 2.0 is in beta, and it's already powering WordPress.com.
