So the honest question is: should we subject industry e.g. blogs to the same standard as the academy. I would think we should hold academic products to a much higher standard. I do agree criticism should be constructive. (One of PRs for example noted lack of mention of CSP.)
Honestly, for me right now, coming from HN into random places, no I don't have different standards. But in a course having a textbook recommendation, yes, the standards are very different.
Anyway, you are out on a tangent. The work should be judged based on its quality, and for all the dimensions quality has, the presentation format is not one that matters.
who is we? are you a tt prof at literally the number 1 cs school in the US? are you a reviewer for any distributed journals? the author of this book is a wildly successful researcher. why should i trust literally almost anyone's here opinion over their opinion?
