Every person that submits a site to DjangoSites gets a chance to include details about how they deployed their website: what database they use, what version of Django they use, and so on.
The aggregated statistics are now online for all to see. The deployment details for individual websites are not visible.
You can see the stats in a basic form along with some pretty charts on the DjangoSites website by clicking the Deployment Stats link in the navigation bar.
I'd love to hear any feedback you've got, please let me know your thoughts via e-mail or Twitter
