I had implemented my photo blog with Wordpress some years ago, primarily as a practical exercise on how Wordpress and I would fit.
Long story short: We didn’t. And I suppose we won’t. While it is true that Wordpress is fine if you need something quickly, from all recent experience, Drupal is my favorite regarding security, constraints and maintainability. (Also, I can now use an existing Drupal multi-site cluster, which reduces efforts again.)
