Ask HN: Whats your preferred CMS for non technical users?

Hi All,

I am looking at building a CMS for a very non technical audience. Rather than re-build the wheel I would like to extend an existing CMS. I have worked with WordPress, Drupal, Joomla and Serendipity. However, none of them is very easy to use for the lay man.

Would it makes sense to build one from scratch or is there something out there that is super easy to use?

Thank you for your time.

Update: I have looked only at the php based CMS since I am most comfortable with php. However the language does not matter, so I am very open to Python, Ruby and others.
