I use org-mode for 'partial' literate programming. It's partial since I only note down the general structure of c++/java classes as a sketch, not actual codes, except for Lisp. I occasionally push the files to Gollum, a git-based wiki supporting org files for mobile reviews.
I've seen some folks do that, and hats off to them; but I learnt vi before emacs, and despite trying to learn emacs a few times over the years, I just never did get to the point where I'd feel comfortable using it for work. So org-mode was always out for me. But it works well for others...
