I teach developers how to use Drupal. I think Drupal is one of the best content management systems out there today, and as developers begin to learn all that Drupal is capable of, they tend to agree that it is awesome.
Throughout the training process and we go through content types, fields, taxonomies and all of the stuff that really makes Drupal shine, people get really excited right up to the point that they get to designing one-off pages.  

What marketers need most is an easy-to-use page builder.
