Michael E. Meyers, VP Large Scale Drupal at Acquia, knows better than most how contributing to the open source project you are relying on to build or improve your business will pay off. He and his team did just that when they successfully built and sold NowPublic.com – the first venture capital funded, Drupal-based startup – while making massive contributions to the Drupal project along the way.
He and I invite you not only to use Drupal, but also to make it better and to get involved with its community. If you're only using it without giving back, you're not getting the full benefit it could be giving you. Come to DrupalCon Amsterdam or an event near you and make a difference!
