Now, though, the templating system and everything else feels rather archaic to me, and I am much quicker to just turn to Wordpress for almost any "quick out of the box" projects I would ever need to do -- WP just works and is so extensible and easy to use, and so easy to skin as I need it. For some instances I could see wanting something more but nowadays Joomla doesn't have as much to offer for me or, I think, many others.
Things have changed lot in the last few years, Wordpress is an honest-to-god cms these days, and people (again, I'm thinking specifically of a few clients of ours) are beginning to understand why learning how to use taxonomies solves some real world problems. Perhaps Joomla hasn't progressed at the same rate. We've got a few clients with Joomla sites, but I haven't considered recommending Joomla for quite some time...

Searching HN for past discussions of Drupal or Wordpress, you get a lot of positive remarks and lively discussions about the pros and cons of each system... just as you would with most any technology.
But Joomla seems mostly negative yet it is the second most popular open source CMS in use! Why do people use Joomla?
