For all the smart people out there that have realized there are very good reasons to choose WordPress over Movable Type... Judd mentions a great spam-blocking plug-in that we both saw first at Alex Halvais' blog:
I recently found a plugin for Wordpress called AuthImage, which adds a simple image-based challenge response mechanism to the comment form. Users just have to type in a short, randomly generated string in order to process the comment. Not too much of a hassle.
