I’ve installed MT-Blacklist, the comment spam blocking program. So far, it’s going pretty well. I’m going to give things at least a week, but after that I may consider turning off comment approval so people will be able to comment immediately even if they aren’t using TypeKey. (If you are, you can still use it to save your information.)
Also in about a week, there will be a major new release of Movable Type; Merv says he’s excited by it. Whenever he installs it there will probable be a window of half an hour or so when this site will be offline.
