First, the Drupal hooks are much improved. I imagine publishers who use Drupal are pretty much exactly the kind of people who would consider Enterprise, and WW have been wise in focusing on getting this part of their envelope right.
Second, the browser-based “media neutral” text editor now support multiple components, i.e. separate holders for headline, byline, body etc. I have always thought this is essential, since I have many misgivings about linked boxes in print publishing, and see the separation of different content types as just plain vital for electronic publishing.
