Localised relays, domain specific relays and relay filtering needs more work in clients. I want the option to push notes to specific relays in a client. We're holy underutilising the vast potential of relays.
Discussion
Peer to peer local relays built into the client with local chat that dissappears after 24 hours or something
Like the Nintendo DS back in the day where you could share notes to people nearby
Spin them up quickly and easily at relaying.io
The conference fedi apps should have nostr based chats and forums.
