I think it can also be useful to discover if there are people that you don't know directly but that have a common contact with you that are interested in exchanging SATs for cash, goods or services.
What’s the user case for these.. it only shows contacts. Why do I need an app to exchange with people I already know? (Real question, not hating) nostr:npub1mftv2j67vayavkks8rqev3u8jjhefe86tf80msstfxvpunk9vmps6prkl3

Mm I get it. Not to discover people but to find people near you, that didn’t know they were coiners too (or wanted to exchange).
