I just spent over a month on a project where we started to use Drupal and I can't see a single thing that is good about it. Poorly written core code. Poorly written modules. Abysmal UI. The only thing I can possibly think that Drupal has going for it is a great community and, as this article mentions, the ability to make a lot of money for little work.

Needless to say, a month and a half into the project we dumped Drupal.
