[tincholio]

I've also used it fairly extensively, both in academia and in industry jobs (using Emacs org-mode, with several target languages, often combined). I found it very useful when thinking through a problem, and as documentation for myself later on. At some point it starts to become a bit unwieldy. Nowadays, most of my work is in Clojure, and I find that the literate workflow gets in the way of REPL-driven development, so I haven't been using it as much lately.

Overall, I'd highly recommend it.
