InfoWorld using Drupal
InfoWorld relaunched on Drupal 6 yesterday! Check out their new site at http://infoworld.com. InfoWorld has been around since 1978 and is a well-known resource for IT professionals. I hope they write up a use case because it is a great testament to Drupal 6.
The project was done by Optaros (an Acquia partner), with help from Airbag Industries for the design work. Chris Fuller was the project lead.
