This is a bit of a tangent, but I really wanted to comment on the product he is making.
I have been using apiary.io, and I always felt that it was lacking in many aspects (versioning, ghetto note editor, parsing issues in the preview, etc...). I just discovered readme.io and played with it briefly and it has solved every issue that I had with apiary.io. I will definitely migrate over, but having to re-do all the documentation from ground up is a bit of a pain.
