When I think about the admin experience of Drupal, I often think about context.
As a longtime Drupal user, it's easy enough for me to know that wherever I am in a Drupal site, there's a predictable spot in the admin menu where I can select a content type and start creating content. For people new to Drupal, or even new to the concept of managing website content, this is nowhere near as obvious. Training will help, but we can also employ the principle of multimodal interaction to provide additional options in ways that will be more obvious.
