Quisition will be very familiar to long-time readers of this blog. The online learning site, which currently focused on flashcards, was first talked about here in 2005. I built a Python + PostgreSQL (but not Django) version in 2005/2006 and ported it to Django in 2006, relaunching the new version in 2007.
Quisition was the site that originally gave me the idea for Pinax. It's also the site that made me want to get back to building websites for a living and start Eldarion. So, as you can imagine, it's very dear to my heart.
The last few months, we've been working on the fleshing out of the topics feature on the site as well as a completely redesign from scratch. That work was completed and launched last week.

I'm very excited about our plans for the site in 2012.
