Right now most clients don’t use relays that host and share just contact and profile information. We were using purplepag.es by nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft until we added that functionality in to our own relay.nos.social. I think using those is a stop gap, but we need a better solution to finding people and contacts.
