I’ve been working quite a bit on Drupal lately. The developers are hungry for users to give feedback, and at least a few people are starting to work on usability issues, myself included. I think Drupal’s got a lot of potential, and I can see using it for a few projects of mine. It’s still not at the point of being as polished as Movable Type, but it’s got it’s own advantages with the way it’s designed and implemented.
