I’ve switched the blog from Movable Type to drupal. Drupal is a PHP based, open source blog and community system that will allow me in the future to support all sorts of fancy things, such as discussion forums, polls, multi-user blogging and a lot of other stuff. Drupal is entirely another class of application beyond MT, though I won’t be using all of what it has at first.
For now, you will of course see a different look for the blog. Categories can be expanded from the navigation menu and you can do more things with them. You can also create a userid and password to log in. If you do this, comments appear under your name and they appear immediately without need for me to approve them. You also can configure how the site looks for you and turn on other features. I can even give users a blog in the future if you like, when the permission system improves. If you have a login at many other drupal sites you can use it here, by using the userid username@thedrupalsite. (Or use email@example.com on other drupal sites.)
Let me know if there are any problems.
