If you have any interest in WordPress and/or Drupal as a technology, or open source more generally, I urge you to find (at least) half an hour to watch this video from a conference in Houston, Texas a couple of weeks back: it's Dries Buytaert, the project lead for Drupal and Matt Mullenweg, co-founder of WordPress sharing a platform for the first time ever.

If you're hoping for fisticuffs, you'll be somewhat disappointed. But it's fascinating to hear the two luminaries explaining their perspectives - the many things which unite them, and the few aspects on which they diverge. It's a beautiful encapsulation of the differing philosophies, structures, businesses and approaches behind the two world-leading platforms... and the strength of the open-source model in general.

There are some audio problems at the start of the recording, but do please bear with it. You won't regret it.
