I've built an impressively simple and basic reusable Django application in the process of creating a mini-CMS for a client. It's called django-chunks and it's really nothing more than a model and a template tag. By adding chunks to your installed apps list in your Django project and performing a ./manage.py syncdb, you'll be able to add as many "keyed" bits of content chunks to your site. The idea here is that you can create a chunk of content, name it with a unique key (for example: home_page_left_bottom) and then you can call this content from a normal template. Why ...
I saw a link to a new CMS in my news reader this morning called LightCMS that bills itself as the first "designer friendly" CMS. When I clicked through to check it out I noticed something odd about their logo. I'd seen it somewhere before, but where? Hmm.... wait! Obama! I see that they've added a few light rays and pulled out the stripes, but the similarity is unmistakable! Maybe they're just huge Obama fans?
