Actually, in terms of capabilities, org-babel is among the most capable, if it is not the most capable, systems for literate programming. I have used it to great effect when learning from computer programming books. I can now go back to those literate programs, and understand again much faster, than originally when reading the books. The literate part of it answers my "silly" questions, that come from not remembering 100% of the reasoning or my own thoughts. That said, there is of course a learning curve, and people unwilling to learn something like that are better off not going that route.
