An anonymous reader writes "PlayingWithWire profiles two open source tools for Web development, comparing Joomla! and WordPress through the lens of usability. The article has apparently upset a few people at the Joomla! forum, but it does bring up a good point. Many open source projects are developed by engineers for engineers — should they focus more on usability? PlayingWithWire makes a bold analogy: 'If Joomla! is Linux, then WordPress is Mac OS X. WordPress might offer only 90% of the features of Joomla!, but in most cases WordPress is both easier to use and faster to get up and running.'" The article repeatedly stresses that blogging platform WordPress and CMS harness Joomla! occupy different levels of the content hierarchy. How fair is it to twit Joomla! on usability?
