Open Source CMS Market 2010 Report Shows Drupal Trailing Joomla! and WordPress
Since last year's report 10 open source CMSes were eliminated based on their current market position. The current list of 20 systems is based on user metrics based on rate of adoption and brand strength, along with surveys conducted with over 5000 developers.
Besides the fact that WordPress, Joomla! and Drupal are still on top, in that order, with no indication that their position will be challenged any time soon. Next on the list are DotNetNuke, Liferay and Typo3.
