Some of you may be interested to know that more than 900 unique participants have been assigned to the development of Django since January 1, 2007. Data based on SVN logs. I must say that the community is very strong, especially in comparison with other well-known projects:
Django: 906
Pylons: 80
PyPy: 240
Linux Kernel: 4043
PostgreSQL: 150
Apache HTTP server: 118
SQLAlchemy: 36
Python: 428
It is necessary to take into account that all anonymous and guest commits were considered as one participant, unless of course the project allowed those.
