I chatted to the builder about modularity in web design & build, and how you have different levels of modularity: "simple" CMSes such as Joomla! and Drupal, through to frameworks such as Rails and Django, on to roll-your-own Languages such as JSP and PHP.

I'm not sure how well this analogy holds up. But what is interesting is the concept of having to learn the system. Your initial choice of system (whether it's a CMS, framework or language) is determined by your needs (now and in the future), your budget and your knowledge. For me, as a lone professional earning an honest crust building web sites, my choice has been Joomla!.
