Dries Buytaert is a man of many interests. He holds a doctorate in computer science and engineering. He is a photographer. He is a husband and father. He is Belgian. However, you may know him best as the original creator and project lead for the Drupal open source Web publishing platform or "the reason there is a DrupalCon in the first place".
In addition to serving as the president of the Drupal Association, he is also the co-founder and CTO of Acquia, a company that offers hosting, technical support, and services for the Drupal platform, and the co-founder of Mollom, a web service that helps identify content quality and stop website spam.
