dotCMS just released a new version 2.2.
The starter website is now based on Bootstrap which is good for mobile users.
I checked their documentation and it seems like a good CMS, although the installation steps can be easier.
A few things I like about this CMS:
- Good plugin framework
- Responsive html design (Bootstrap)
- RESTful XML/ATOM read/write
- Related content, filtering of related content
- WYSIWYG editor (TinyMCE)
