@cocoasamurai One said that if I was just going to copy the ReactiveCocoa README I might have just not bothered.
Trying to take it positively and come up with ideas for appendices I can add for the next release of the book.
I've had nearly 600 people buy my book on ReactiveCocoa. 3 have returned it, which is good, but they leave the most hurtful comments when they do.
Comments aren't public but still, not very constructive.
