This is something I'm trying to address with my startup, Krewe: https://www.gokrewe.com/about. I want to make it easy for people to quickly form strong, lasting friendships and relationships and become connected with their local community. It gives people access to a small social group in their neighborhood and gradually allows them to expand that group. Since everyone lives so close to each other, it makes it possible to get together often, even everyday if they want, without having to deal with extensive planning or traffic.

If YC or anyone else wants to fund me, I'd be fine with that.
