So I once happened to be at a company where I was lucky enough to have several colleagues join me in an SICP reading group. We squatted in a conference room once a week and plowed through as many sections as we could during lunch.

The key feature of the reading group, I thought, was that we were able to identify, right in our production code, right there in the conference room, instances where we used particular idioms from the SICP section under discussion. It was that identification of actual fancy SICP concepts (in scheme-world) in the familiar production code (java-world) that made this particularly worthwhile; folks (including me) saw a whole bunch of places where our java codebase would be (or had already been) improved by applying what we were reading about in the book. It was among the more useful exercises of my professional career so far.

So perhaps this django-based discussion group could include illustrations from a reasonable open source codebase (django itself?).

Sounds like great fun.
