#1: Wordpress /is/ horrible. One of the worst projects I have to deal with for work... (in the OT subthread where I talked about immutable $_POST, that was inspired by some awful code inside Wordpress!) The template system (see next) has lots of required boilerplate and ugliness too. Take a look at twentyten/header.php for some examples. #2: Even Wordpress doesn't mix code with output very often - it uses a template system too - the themes folder. Sure, PHP is it's template language, but it does separate the main code from the template code. It fits under the category of disciplined php I touched upon in my document. I don't know drupal so I can't comment on that.
