Usability is a major objective for Drupal 7, the new upcoming version -- so much so that they've set up a site entirely devoted to it called, 'Drupal 7 User Experience Project' -- or 'D7UX.org' for short.
You've got to love a site which wears a declaration like this on its sleeve:
"Our UX Principles: 1. Make the most frequent tasks easy and less frequent tasks achievable. 2. Design for the 80% 3. Privilege the Content Creator 4. Make the default settings smart"
It's the first thing you see!
