Thanks for this explanation. This is one of the things that popped out at me when I looked at the book page. The statement about not providing answers seemed quite dogmatic, and my initial reaction was, why? Turns out it's not so dogmatic, and there's a thoughtful and nuanced explanation. Perhaps you could include some of this on the book page, or provide a link to the explanation elsewhere.

Completely agree - being outside academia has apparently made me ignorant to a lot of the pitfalls to actually posting said solutions.

Makes perfect sense when put this way.

I also really appreciate the response from the author. I forget the gurus behind books like this often have a presence here on HN.

Not always the case though Prof. Erickson seems to be the exception
