I really like this comment. But I bet some folks gloss over a particular point of importance. For me, there's a huge advantage in literally using tree-paper, either for code-reading, designing, taking notes, what have you. It involves more of your senses, it's more tangible, every letter is written with more care and the medium is incredibly flexible (maybe I feel like drawing a circle on a whim, can't do that in emacs.) It's better for scratch-pads than a text-buffer, imo. Insights come more consistently and easily after iteratively marking up a printout. It's just fully-intuitive.
