I've decided to keep the blog going but move to Blogger from my generic web-hosting provider. Nothing against them, they have been great, but I can't justify even the small amount I am paying them when I am only using the service to host a Wordpress installation. When I'm ready to start building actual web apps they will be the first place I will go.
I had to do a lot of finagling with my registrar to try to get the old domain name to point to the new blog, and it will be at least an hour before I know whether everything is set up correctly. For now ajustmachine.com pulls up a Google 404 page. I guess the fact that Google is responding is a somewhat hopeful sign.
Update: www.ajustmachine.com now points to this blog, but the bare domain name does not. It may take a while longer for the A records to propagate (look at me, dropping hard-core DNS terminology.)
Update 2: looks like I missed the setting that auto-redirects the bare domain name to the www address. Now ajustmachine.com works, too. Hooray!
