Today, the White House announced it was changing the platform on which the White House website is built. Why are they doing this and what does it mean? The intent is to make the site more interactive by allowing people to participate in discussions as a community. The site will be based on the open-source Drupal Content Management System (CMS). Drupal is widely regarded as the most well-developed CMS for launching community-driven websites and ranks near the top for the most popular and widely used CMS. Drupal, like other CMS’s, can be used for everything from a one-person blog to a mass media news organization like CNN. It is built under the open-source model where anyone can contribute to the project by writing modules, plugins, extensions, themes, and even the source code. The adoption of Drupal by the White House is the highest-profile endorsement of both Drupal and open-source programming and it comes as a surprise because most enterprise and government IT uses Microsoft Windows.
