Mostly for the federated bits I assume. Being able to follow people’s bookwyrm accounts from your other socials is an interesting idea, though I don’t know how often it actually happens in practice. If that stuff doesn’t interest you then yeah just use OL directly ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯

IIRC bookwyrm lets you search openlibrary for books if they’re not known by your server or some well-known instances like bookwyrm.social
