As you may remember, I use MarsEdit to compose posts, and Movable Type to publish them. I’ve just upgraded to the most recent versions of each. Unfortunately, there seem to be some incompatibilities that are not making me incredibly happy. For one thing, when I want to choose the text format for a post, I get these options: 
That doesn’t look quite right. For another, Movable Type 4 supports entering tags for posts, but I can’t find a way to enter tags within MarsEdit. That said, I’m generally really fond of both upgrades. Both Movable Type 4 and MarsEdit 2 offer vastly improved support for embedding images in blog posts. What that means is that you’ll probably see more images used around these parts. The way templates are handled in Movable Type 4 is really impressive. I haven’t dug in completely yet, but the templating system seems more intuitive than ever. More like a real content management system and much more flexible in enabling users to build pages out of components. The one big Movable Type problem that continues in version 4 is poor performance, especially on the back end. Movable Type remains a CGI application, which really is sort of quaint. That said, I installed FastCGI and am using it to speed up Movable Type. The difference is noticeable. I’m still ironing out the kinks and I haven’t even started messing with the design, but overall I think this upgrade is going to wind up working out very well.
