The Django version of Quisition is just about ready to be deployed. I'm just waiting for the chapter on deployment in the Django Book to be published :-)
The Django version will be an open beta, even though it is a complete rewrite of the previous closed beta. I haven't added much functionality to what was in the closed beta. In particular, you can't add your own cards yet (but that will come in the next few weeks).
The biggest improvement (besides being written using Django) is that I now separate the notion of a "pack" from a "deck". A pack is a collection of cards distributed as a single unit. A deck is a collection of packs that are to be tested as part of the same session.
The main motivation is in cases like learning vocab from a book, where it is easier to manage a pack of cards per chapter but, when it's time to learn a particular chapter, you just want to add the cards in that pack to your deck.
So say you're learning Biblical Greek. You could create a deck for "Biblical Greek" and add to it the pack for chapter 1. When you are ready to learn chapter 2, you can add the chapter 2 pack to your "Biblical Greek" deck. This will also facilitate the creation of new cards for a deck that has already been started on.
