My local library used to have people meeting up to play chess too, doesn't seem to happen much anymore. Also tied in with libraries turning into less library-ish spaces, lack of funding, poor stock of books (sometimes they'll have the latest book-slop but don't have some basic classics, literature, philosophy etc).
But yeah imagine a social media that you have to physically clock into the library once in a while to use. Perhaps with chess online lol, but even better in-person, meetings, book clubs and what not. Something like this would be amazing.
I know this happens already, but I mean if this was on a bigger scale.
