Here’s a link to an interesting question on Quora about WordPress vs Drupal that got a thoughtful answer from Dries Buytaert, the guy who created Drupal. A number of the other answers are pretty interesting too. It’s actually an older question, but it rose to the top of my Quora feed today, for some reason. Quora is sometimes very good at surfacing useful answers to questions, and avoiding the flame wars and trolling that would normally clutter up any “X vs Y” discussion on the internet.
And, hey, here’s an article on migrating from Drupal to WordPress. I’m curious as to why anyone would want to do that though. If you already had a site up & running in Drupal, what would you get by migrating to WordPress? I could see cases where you’d want to go in the other direction, since Drupal has some functionality that doesn’t exist in (base) WordPress. I guess I could think of a few cases where you’d want to go from Drupal to WordPress, if you were dealing with a simple site and didn’t need all the overhead of Drupal, and/or wanted the WP admin interface, which (for some things) is nicer looking & friendlier than Drupal’s.
