I really like the koans format of language learning. I find they pique and sustain my interest more than rote tutorials or trying to glean purpose, feel and function of languages. It feels much more like a puzzle, the hints can be more cryptic and requires me to be more bought in than an introductory podcast or an online set of lessons. I'd love to see this format applied to other topics and fields, although none will likely lend themselves to the format as natively as programming languages will.
