Drupal is a highly scalable, flexible and easy to use open-source CMS. Some unique features of Drupal are:

    - Drupal is SEO optimized, most CMS dont
    - Granular user permissions is inherent to Drupal
    - Out of the box multisite management in Drupal while its not present or not mature enough in other CMS's
    - Internationalization features is focused on in Drupal 6 while other CMS dont focus much on multi-lingual sites.

No wonder, Drupal was the choice of some of the best awards among its peers. Drupal won the CNET 2008 Webware awards in publishing category and also the Packt Publishing’s 2008 - Best Open Source Content Management System. This is because, drupal provides both open source CMS as well as Framework. Where as, other CMS like Joomla provides only open source CMS.

The biggest advantage of using Drupal is its highly involved and growing community of developers and contributors which keeps it going. Owning to the active Drupal community, it is very easy to find new and contributed modules, patches to bugs find in the system and subsequent documentation.

It is this active community that has helped Drupal bring out new versions almost every year with the latest being Drupal 6. The core contributors of Drupal are committed to making it more useful to the community and hence work has already begun on how Drupal 7 would look like.
