The first day of Drupalcon Szeged is underway, and what a day it's been.  We've already heard from Dries Buytaert about the current State of Drupal, and the future of Drupal, and now I have the pleasure of listening to Rasmus Lerdorf, the creator of the PHP programming language.  It's opportunities like these that really make Drupalcon (and Drupal in general) such an amazing experience that would simply be impossible with a closed source solution.
