@mapto Your exact wording was:
someone focused on money would have much more “valuable” (in market terms) bookstore. Someone into books would have something that doesn’t necessarily sell well, but relates to others passionate about reading, e.g. niche literature
This seems to imply you see large money-focused bookstores as focusing on popular books while less money-hungry book stores might focus more on obscure books.
I argue this isnt the reality. In fact a much more money focused bookstore will try to have everything, and cater to both the obscure crowd and mainstream. Which is exactly the case with amazon.
