Recent New Comer WebriQ stirs the pot with their Disruptive Technology while the majority of people are still only discussing Wordpress, Joomla and Drupal as the three best Open source Content Management Systems. These systems will be reviewed through first hand experience. But, we will add to the equation, a Commercial Open Source CMS system called WebriQ 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).
In contrast, Commercial Open Source systems are build on open source technology but are bundled as a software service in a service platform with a large amount of standard features embedded in the platform. Those platforms have a tendency to eliminate the FUD factor when implementing the latest web technologies, they eliminate the proprietary licensing fees, they are lowering the cost of ownership by simplifying development and maintenance efforts, they are delivering a scalable solution that meets the demands of small and large enterprises and they are enticing both the Business owner and the Web Developers alike. The last point being the key difference between the open source platforms and the current available commercial open source platforms.
