I will stop associating arxiv with solely research papers now. I guess they getting filled with lots of these so-called "whitepapers". I appreciate the effort of this paper, though, it seems more like an idea for a textbook. It even seems like arxiv is welcoming this what with their "Computers > Learning" breadcrumb, good to see more types of educational documents in the research realm, but I feel that teaching and research are separate for a reason.
