The State of Open Source Content Management Systems in 2011

What happened in the world of Content Management Systems (CMS) last year?

Drupal, WordPress, and Joomla! continued their reign as the most popular Open Source CMS for the third year running, according to the 2011 Open Source CMS Market Share Report by Ric Shreves of the digital agency water&stone. While WordPress was downloaded more than any other CMS, Drupal was the most popular based on numbers of messages, blog citations, and references in social networking sites. A survey of 2,500 people showed one-third of the respondents used WordPress, followed by 20 percent who used Drupal.

Joomla! and Plone are showing signs of weakness. Joomla’s usage peaked in 2009 and is now downloaded less than half as often as during its heyday. Similarly, Plone is seeing high abandonment rates as users switch to other systems. Concrete 5 is an up-and-comer to watch and is rapidly gaining new users.

In any case, most survey respondents were very happy with their current CMS choice. Nearly 95 percent of respondents said they would recommend their present system to others. But Shreves’ report also indicates that people are continuing to change up their CMS, with only 44 percent of respondents using the same CMS as they did three years ago.
