Whilst the majority of people are still only discussing Wordpress, Joomla and Drupal as the three best Open source Content Management Systems, more and more commercial Open source Content Mangement Systems are launched. These systems will be reviewed through first hand experience. But, we will add to the equation, a Commercial Open Source CMS system and analyze the major differences between the three open source system and then group those open source system and compare them with a Commercial Open source system.
Only within the last year has Wordpress actually begun to step up as a true CMS. However the other two, Drupal and Joomla, have seemingly always been fighting for that top spot in the community. Both are open source, and both are widely developed with thousands of members in their community helping to develop and extend the possibilities of use for each. While Wordpress is considered the underdog in the CMS war, it is most definitely the king of blogging software (something that Joomla and Drupal struggle to do efficiently).
