I admire your optimism, but statements like "Who wouldn't want X?" are inherently naive. When you ask people if they'd want X, they generally answer yes. What matters is what people will actually do, and I don't think it's possible to build a product like yours without a very keen understanding of that.

I'm well aware. I don't often pitch it like that. It's only in the context of whether Krewe can be a unicorn do I bring it up. There are 60 million people in the US alone who say they're lonely. I think it's safe to say that those people could use a few more friends they have access to. But I haven't found it to be a hard convince any one else how much better their life would be if they had many more close connections. The problem is just getting enough people to listen.

I feel like facebook could create such a thing without effort. They should already know whee you are when you're at home, so they could make groups that cluster people by location.

Cue mainstream media going wild on "Facebook wants to dictate our friends! OMG SO UNCOOL!!". It would need some careful branding, easier done by another company.
