The people behind the Schipulcon event managed to get both Matt Mullenweg and Dries Buytaert (of Drupal fame) together for a talk on open source software competition and open source communities. Running around 54 minutes, the video (embedded above) is a great watch if you want to hear these two competitors have fun talking about what they do and the community they’re involved with.
Forgive the audio for the first few minutes. It gets fixed around the 4 minute mark.
What do you like/dislike about the open source community?
