Goodreads is perhaps the best example of enshittification imo. It’s only good now as a way to track your reading lists.
I tried bookwyrm today and it feels quite polished already, like giving you a guided tour of it’s features. Hopefully it takes off as well similar to mastodon and lemmy.
Late response, but there is BookBrainz, the book-equivalent of MusicBrainz. It’s catalogue isn’t as big as OpenLibrary but they’re doing way better on the front of keeping their data clean and without duplicates. I hope someday it will find more users and be the base for other apps to built upon.
