How did django-annoying (https://bitbucket.org/offline/django-annoying) not make the list? I find the stuff in django-annoying to be crucial on any Django project I do (the render_to() and @ajax_request decorators especially).
I tested out the class based views in Django 1.3, but decided that I didn't like the complexity that all the MixIns added. I was constantly having to remember which things each MixIn added to my class. I found it simpler to just do function based views with several decorators.
