Today I read a Report from Water & Stone, a big name in the Mambo community as one of there Templates is a great looking one with a lot of installations.

The report (which you can download here) brings numbers and conclusions on Market shares of Open Source CMS like Joomla!, Drupal, WordPress and many others like e107,Typo3, Modx, Elgg en more…

In the report there are clearly three Big names in Open Source CMS, not that we did not know who the leaders are, but Rik Shreves does a great job by bringing in the numbers to proof it!

What is strange to me was that Twitter users tend to write more on WordPress and Drupal than on Joomla!, Where are the Joomla Twitters?

I also like the Search Engine Ranking research on page 17, on which Joomla! and Drupal score big time, but WordPress is nowhere in sight for the search terms that contain CMS.
Clearly WordPress is still mostly seen as an Blogging platform instead of a Content Management System like Joomla and Drupal.

In the conclusion pages of the report there is also a section about the future of some projects like Mambo en CMSMadeSimple as well upcoming systems like Elgg and Modx.

Get the download and read the report, it is well written with lots of graphs and gives an insight of what the market in Open Source CMS is right now!
