In case you haven't already heard, TypePad is now in public beta and is definitely worth checking out. The posting interfaces are simple, powerful, and sublime. I've also found that after playing with Typepad's mobile blogging and photo blogging features, I never want to upload photos through my current crude methods on this site. The system they got there is so refined and easy to use, I can't wait until the innovations trickle into a future Movable Type product (or I guess I'll wait until they support custom domains at typepad and just move my site over there).
