At the moment I’m mostly just annoyed by having to remember the very minimal CSS that I’d once figured out as well as trying to comprehend yet another theming system.
But I achieved the two basic things I wanted: post speed is higher by default and I can post from my phone easily. So I figure I may as well just go for it.
I think I’ve managed to keep old links working thanks to all the static html MovableType left around for me.
