Ooooh nice! I started a sort of tangentially related list, if you wanna poach anything from it: https://books.theunseen.city/list/535/s/we-dont-have-to-live-like-this

Actually thia raises a question. Bookwyrm lists clearly must federate, because you can interact with lists hosted on one instance from accounts on other instances. But what are their fedi handles??
