The difference there is becoming vanishingly small. There are _many many_ sites out there using WordPress as a straight CMS with no blog-like functionality.

I've used and deployed both - if I'd _ever_ been able to get one single client to understand the power of Drupal's taxonomies, I'd be developing and deploying Drupal sites everywhere. As it turns out for me, clients are _much_ happier with WordPress's backend/ecosystem/documentation.

I just get annoyed by the Drupal admin panel's absolutely boneheaded UI + missing features and slow performance - D7 was supposed to help with this, and we barely got a new admin theme. Wordpress isn't as sophisticated, but the UI is nicer and it has the basic functionality out of the box
