There is this really cool website: https://fediversemap.com/
that shows fediverse instances that are physically close to you.
i think this is a really cool idea because it allows connecting to people that you can meet in real life. it allows organizing of offline events, and that's something that i think we can all use very much.
I would like lemmy to integrate a list of instances that are physically close to you, sothat you can easily find and connect with them. maybe you can automatically browse through their communities and find communities that are relevant to you. communities i.e. about cities that enable organizing and scheduling events.
