I missed this article in previous rounds, but during your interview with the Changelog regarding RedwoodJS I remembered the anecdote about "writing the tutorial first" and it really stuck with me.

I find this especially useful when I'm building complete solutions from lots of other technologies -- it's easy to fall into the trap of "well my API will behave like API X because that's what I'm using under the hood". Readme driven development really encourages thinking harder and producing something that's greater than the sum of its parts.
