This evening I gave a presentation at the Software Development Network about Drupal. Because the seminar is mainly focused on application development and closed source, I was the odd one out talking about PHP. All other topics were DotNetNuke, Delphi, Umbraco, Silverlight, SharePoint, etc. That said, I was rather surprised to find an enthusiast audience who were impressed when I told them that large sites as The White House, The World Bank, Ahold and even Java are running on Drupal!
