Would also like something like this! I understand the fear of depending too much on scores, as they don't always say much, but something like "users similar to you liked this" or "this book has this and this and this which you marked as features you love" etc. Very specifically, I'm in a book club where we try to diversify our reading, so we do different genres every time. And I'd like to filter through books from a genre I might not read often and still get a suggestion I'll probably like (e.g., I rarely read thrillers, but when I filter by 'thriller', it would be cool if I could sort that by 'liked by readers similar to you' or 'has x features you seem to like in other books' or whatever). We now often take the Goodreads top ranked as a starting point but I feel there must be better ways to do this, and the Storygraph has the info to do it I think)

I really love this idea, even if it is something general like "readers like you liked this book". I get a lot of book newsletters and spend a bunch of time looking them up on Amazon to see if I would like them. I'd rather look up here and see some indication of how people with reading profiles similar to mine felt about it.

An interesting idea for sure!

We've been wary of doing something like this because when I was originally researching the books product space, something that came up was a distrust of algorithms and how everything these days is an algorithm telling you what you would like or wouldn't like. That's why we mainly went down the: "tell us what you're interested in and have a chance to change that whenever you want" route — taking advantage of an algorithmic power, whilst still giving the user some control.

If something like this is only an element of the product though, as you suggest, and not the only way to get recs, it could work!
