Would be interesting to see how well a marketplace inside such a service would do. My guess is that people would fork it and just replace the marketplace with magnet links for torrents 🤷♂️

a nostr goodreads could just be a listr fork to start off with
Hmm how would that work?
you need to be able to create a list of books (which would be a new kind of listable item), ability to follow others lists, fork lists, review books (similar to hoe wikifreedia and gitworkshop supports comments)
I haven't dug too much into NIP-54 but I'd imagine you could leverage that to build a set of book descriptions and then you could build your own lists of books with references to those wiki pages
