Mike Gifford, Open Concept, commented here at CMS Report that his company had just posted a report they did for a client comparing three open source content management systems. His company needed to recommend to their client whether Wordpress, Joomla, and Drupal would be a good replacement for their current CMS, Back-End (BE).
We've just done a report for one of our clients comparing Drupal, Joomla & Wordpress for (1) multilingual capabilities (also called internationalization or i18n); (2) end-user usability; and (3) developer usability.
As a national organization in Canada, being bilingual was a must. Check out our CMS comparison.
This is a good report and I'll let you read it on your own to find out which CMS they recommended the client utilize for their next CMS. I like the fact that the analysis compared criteria consistently and observed pros/cons in each of the Web applications.
I also find it interesting that they referenced a post I did last year comparing Drupal and Joomla as well as an article from Gadgetopia's Dean Barker. It's interesting in that both Dean and I have both gotten a lot of mileage out of those posts and it shows just how much we all feed from each other when it it comes to writing about information technology.
