On second thoughts, it could be good to have it all integrated and all powered by Django.  We're getting along OK with Drupal, but in many ways Django would be better - provided someone has the time to set it up.  A Django project for it would be able to use a filesystem-based content management system (e.g. djangoproject.com's code), so we could use Bazaar for it and pull and push content very easily without needing to log in to the website, etc., and (BIG plus here which we just can't really do properly with Drupal, so we wouldn't be able to have a purely Drupal system) could also replace the MediaWiki wiki properly with py-wikimarkup (we could then also gradually shift over to reStructuredText which is the recommended - and very good - documentation, etc. format; lots of things use it, say even that py-wikimarkup readme file is RST).  The more I actually think about it, I think that doing the Inkscape website in Django would be better.  It would take a bit longer than Drupal to get started for just basic content and all (is there anyone else in the community familiar with Django?  I won't have endless time, I'm working on my own commercial Django project), but it would be much faster for other things - say the wiki, and an extensions repository - and it would all be integrated.  I think we could still get it up and going before 0.48.  I think that if we have a couple of other people who can do Django stuff, we could probably get it integrated faster than Drupal.  Not needing to worry with moving from a file-based content system to a database-based ditto has some great advantages.

I change my vote from Drupal to Django.
