So I found this website (via junkmail please judge me) called "next-door" its sort of Twitter/Facebook style posts but from everyone with the radius of the zip code you set.

It has a marketplace section (so this is specifically a local marketplace) it has local business pages it has a concept of a "help map" so if you can help during winter storms or other emergencies you can put yourself on that map and it has pages for local meetup groups.

The only problem with it, is its not a nostr app! Nostr apps are very Twitter like right now and this platform is much closer to that Facebook feel.

I think someone should make a nostr app based around the idea next-door is going for which may involve extending the protocol to include zip codes so that users only receive posts close to their zip code. I believe this will also be good for Bitcoin circular economy growth. nostr:note1gcdfpa4z80c2c65dcn0ct45amlvkufqqtuectcyv0q8r9rfmcclstyn7d5
