I recently did a new Movable Type 3.11 install for a project. Relatively painless if you've been through the process before, or are an experienced sysadmin. This version has improved comment management and dynamic page generation. I'm on record as being against using Php for MT dynamic pages, but it's sort of a neat trick how they do it. mod_rewrite and error pages are used to forward non-existent pages to Php. Then a Php library that reimplements the MT Perl API takes over.
As I said, I'm not a big fan, but I think this does raise an issue that's going to become more important in weblog tools and cmses in general. Allowing the smooth transition between statically and dynamically generated pages. There are all sorts of tradeoffs given the demands of popular vs unpopular sites, frequent vs infrequent authors, and sophisticated vs naive publishers. How do you design a gentle slope system that let's folks intelligently select parts of their site for dynamic or static generation?
Apropos of nothing, one thing about MT that really bugs me, is the inability to actually refer to one lone entry. Say you have one outstanding post that you'd like to refer to in a template. There literally is no way to do so using the MT template tags. Sounds like a useful plug-in opportunity to me.
