One aspect of Django that never ceases to amaze me, is how well it is documented. I believe this aspect of the Django project got many of us to use it, me included. While doing some boring graduate donkey work, Django’s name popped out, and not surprisingly, as one of the highly documented code bases out there (only projects focusing on documentation came close!). So lets me take this opportunity to thank all those who might be reading this, who had a hand in making Django what it is (Thank you!)
The Lines of documentation to SLOC ratio is plotted against SLOC for 1st of Jan, 2009. Django has one of the highest ratios compared to other open source projects of similar size (See the top part of the Graph). Of course I could have plotted doc lines to SLOC, but then I have to show the deviation of Django from the regression line. This graph just makes it more obvious and is easier to plot:

I also have a few questions should any Django contributors pass by. Any of you guys think that you might have over done it? Is it difficult to maintain the quality of the documentation and keep it up-to-date and did anything change after moving to a regular release schedule? Is it only contributors experienced with the Django code base, who are able to write documentation to ensure quality?
Since I also live in a world where ponies roam and correlation is always seen as causation, let me end this post by saying:
Good documentation is the cause of success for Django, and high ice cream consumption is the cause of increased deaths in neighborhoods with swimming pools during summer!
