WordPress: FREE blog publishing tool for your desktop. If you feel ready to use your ISP's PHP service and set up a blog on your own site, this is the application for you. I haven't tried it yet, but they seem to make it really easy at WordPress. Lots of demos, tutorials, etc.
"WordPress was born out of a desire for an elegant, well-architectured personal publishing system built on PHP and MySQL and licensed under the GPL. It is the official successor of b2/cafelog. WordPress is fresh software, but its roots and development go back to 2001. It is a mature and stable product. We hope by focusing on user experience and web standards we can create a tool different from anything else out there."
