"Programs must be written for people to read, and only incidentally for machines to execute."
- Abelson & Sussman, SICP, preface to the first edition
We know as a fact this is not followed. Code in a hackathon is usually proof of concept for an idea, not launch ready code. Who needs a kernel/proof-of-concept math book with all the existing content out there? Do more harm than good IMO.
Big plus point for the collaboration effort though, which probably would not have happened otherwise.
Good point, however, there are no free textbooks that are made by collaborative effort. This book is also free to edit, so teachers can take parts out, add parts and so on.
This book is definitely written "for people to read". It is very clear and understandable. One could think that a text book written over one weekend is very messy and hard to read, but this was indeed not the case. The writers especially focused on making the book as easy to understand as possible.
