I don’t really know what the dev’s roadmap is, but I do think that reccomendations shouldn’t even be a part of the instance beyond recommendations from your “community” or people who you follow. I think it should be a seperate service/website that imports your goodreads/bookwyrm data and algorithms it while serving ads. It can then push recommendations over to your bookwyrm home instance with activitypub. Otherwise each instance will need the data from every other instance just to give you recommendations based on what other people like you enjoyed.
