The most important part of Django is it's community of contributors -- without contributors, Django would never improve. However, while it's relatively easy to work out how to use Django, the process of getting involved in development is a little more opaque. How does the the core team operate? What tools and decision making processes exist? And how do you, as a Django user, get involved?
