CMS Expo in Chicago last week gave me a great opportunity to learn about a variety of content management systems. I spent most of my time at the conference getting out of my comfort zone by visiting with those companies and open source projects that I knew the least about their products and services. Unfortunately, this strategy also prevented me from visiting with my personal favorite CMS, Drupal. By the end of the conference, I felt I needed to treat myself by attending one of the final sessions in the Drupal track, Social Drupal.
