We use nginx and FastCGI for all of our Django deployments. This is mostly because we usually deploy over at Slicehost, and don't want to donate all of our memory to Apache. I guess this would be our "use case".
As for the remarks about the documentation being mostly in Russian -- I've found most of the information on the English wiki to be very useful and accurate. This site has sample configurations for Django too, from which you can tweak your own nginx configuration.
