I think one of the interesting with Django is just how easy it is to get started with it without prior programming knowledge. I believe this has to do with Python itself and the great docs on Djangoproject.com
Just start doing the tutorial and voila. This has introduced a large amount of new programmers to Django and Python, making it gain in popularity extremely quickly. Case in point: when Django 1.0 came out the "core team" was often on Google Groups "django-users" answering even the most basic questions about programming.
Now most have moved on from Lawrence to businesses of their own; e.g. they're building cool new things. Other users within the Django community need to take over the baton and build up the community. I truly think there are tons of developers out there that are just using Django and haven't taken time to contribute back (I'm partly looking at myself) I think a new surge can take place in Django development in that respect; the user base Django has accrued over the years need to start returning the investment as it were.
Speaking for myself, I've been able to find most if not all information I needed online, and haven't so much needed to go to meetups or even irc and google groups. In this respect the lack of Django community you speak of rests on my shoulders and other Django users out there who haven't taken the time to contribute back to the community.
EDIT: I'm going to make a point of being more involved in the community via IRC etc.
