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.
In Whakoom, a spanish website to keep track of your comics collection, they have this functionality to add different editions to the same book, so they are linked and you can search other editions when you’re seeing the book details.
