I came here to comment just this. I downloaded it for fun and was stoked to see manage.py! Interesting indeed to explore others' conventions. I particularly like settings as a module.
One thing I tend to avoid, however (of course this is just my personal taste) is templates in each sub-app. I feel like at that point there are just too many nested directories. I'd rather have one global templates dir for the entire project.
I often-times argue with myself over this. I do agree that one global template dir is nice but it makes the apps less copy-and-paste-able and I feel like Django apps were meant to be somewhat self-contained.
However, sometimes you have so many cross-links between apps in Django projects that taking out a single app to use in another project basically breaks most of the functionality.
There are big pros and cons for doing it either way.
