Selecting a Content Management System (CMS) is never an easy task. So when IBM Developerworks wrote an article on "Using open source software to design, develop, and deploy a collaborative Web site, Part 1", it quickly caught the attention of many webmasters who were keen to see which CMS was chosen by the team of Senior IBM software engineers.
The team compared Drupal, Mambo, Typo3, Movable Type, Wordpress and Text Pattern packages. At the end of the day, they chose to use Drupal based on a number of features including Themability and Session Control.
The IBM guys actually get down with the job, providing a good, objective and sensible look at how to choose a CMS by actually working on a dummy website, built using Drupal 4.6. Screenshots of the website can be found in the article mentionned above.
The article, the first in the series, has been written using Drupal 4.7 which shows how dynamic the Drupal community.
