Videos of the sessions from Drupal Camp London have started to appear on YouTube including some vox-pops style interviews from attendees. In this short interview [YouTube], MySQL co founder David Axmark gives a warning to the Drupal community. David makes a couple of observations about Drupal, drawing parallels between it and MySQL. After saying that most of the money made by MySQL was with small companies using MySQL for consulting, projects, and building websites, he says: "you have LOTS of companies building Drupal websites, they are the base bone of the Drupal community, it's not the big guys."
