Some of us lack access to good physical bookstores which are curated and allow for casual non-biased exploration. Amazon and other digital players never picked up on curation or segmentation, their store fronts are hot messes similar to digging through a random bin of books at a second hand store. To top it off they skew your opinion with customer ratings visible next to every single title.
So a list like this is a somewhat working digital alternative to browsing books in a curated bookstore.
