You nailed another disctinctive aspect of MODx : it empowers peole to create because it’s so flexible, but also it speed up the development process by making your workflow "shorter" (less steps) and believe me much less time doing maintenance !
I speak from experience, currently working on a big Drupal project I feel the difference
Don’t even get me started on incompatibility issues between modules... I recently lost a day’s work trying to figure out which of the 120 modules my project is running was screwing up with the forum’s post (they were no longer visible). Sure, Drupal has so many modules it’s bound to happen more than a CMS which has less addons but still... Now I am documenting everything I do !
I think once MODx gets some key addons rolling (intranet/extranet and advanced community features), I’ll never work with another CMS, period ! I have faith that Revolution will open a new era in terms of addons development and this hopefully will open many new doors !!! Not to mention a nice usability improvement with the new manager
