100%, book tracking isn’t a new thing and as you say there are others out there doing something similar.

First difference I am going for is building this on the open social graph that Nostr offers. This has some really interesting opportunities for social engagement, cross-application conversions, avenues for authors to directly connect with and monetise their content. I’ve also built it on the Open Library stack which offers the possibility of getting books into people’s hands as they do have a range of books available to be borrowed. Further out I am looking at how with integrating things like zap.stream it could be possible for authors to have direct video dialogue with fans (book readings, interviews etc.) and maybe even allow independent book sellers to have nostr powered shopfronts in OL.

As for what I think something like Open Librarian can do for Nostr, I believe it could make the protocol more approachable for non-Bitcoiners. I am also thinking that this sort of specialisation is critical to Nostr flourishing, I will not be building the regular fire-hose of kind 1s into the app but am instead thinking about tailoring the view to books (and related) content by maybe using tags for feeds and topic specific ‘chat rooms’.

Outside of that I and hoping to strike the balance between fun social book tracking app and not being a drain on people’s time. Let’s face it we’d all like folks to spend more time reading than scrolling the socials!!
