The "All Buttons Pressed" project
This is the the website you're currently looking at. All Buttons Pressed provides a simple "CMS" with support for multiple independent blogs. It's compatible with Django-nonrel and the normal SQL-based Django, so you can use it with App Engine, MongoDB, MySQL, PostgreSQL, sqlite, and all other backends that work with either Django or Django-nonrel. Actually the project was started to demonstrate what's possible with Django-nonrel and to give you an impression of how to write code for non-relational databases.
Documentation will follow, soon. Some parts of the code are explained in the 4 things to know for NoSQL Django coders blog post. In any case, after manage.py runserver you should go to http://localhost:8000/admin/ and create a few pages and posts. Otherwise you'll only see a 404 error page. Also, for the CSS files you'll need to install Sass.
