Useful and fun. Enjoyed meeting the folks from Top Floor Studio as well as Doug Vann, John Paul McNeal, and many others. I often find that at conferences, sometimes the most valuable information exchanges are the casual ones that transpire during breaks. Heard DrupalCon Chicago '11 is expected to draw a ridiculously large crowd. (Reserve early). And the NYSE, which dropped some expensive propreitary web solution in favor of Drupal, is set to release a slew of Drupal-based sites before year's end.
