Whatever the case may be, I can take a single VPS and multi-host a bunch of domains, each with it's own Wordpress installation, DB, etc. Virtual hosts makes this possible. It's stupid simple. Getting a single Django application running under a single domain on a VPS is a nightmare. Particularly when you consider everything you have to do to migrate from the development environment to production.

This is why we do not do any Django development using the standard installation and go right wo running it just like production on either virtual machines or a dedicated on-premises Linux server. The development environment is as close to an exact match as the production environment. No SQLite, no runserver, no nonsense with static files, etc. This is what I think the Django project needs to really think about working on. There is no reason to have a crippled development environment at all. The base installation ought to be setup to migrate to a standard Linux host (not something purpose-built like Heroku) without much friction. If you are doing a more complex site with multiple servers, load balancing, etc., you are on your own.

I truly think adoption would be far greater if the deployment experience was sensible. I have talked to people who absolutely gave up on Django because going from development to production was a nightmare without spending money on far more expensive servers and services they should. This is an application (Django) that should easily run on any Linux server. The fact that companies were created to facilitate deployment says it all.
