Well then you'll have to explain what you mean every time. And outside Nostr it will be even more difficult. Make simple things complicated because of "unique to my perspective in the graph" is still make simple things complicated. If some client or product ever becomes the main one in using the protocol, then it will not be surprising that the name of such a product will become dominant in everyday life, and instead of "on Nostr" there will be something like "in zbd universe". Until then, no matter what client, what relays or networks, who follows/communicate/block/mute who, we're all using the Nostr protocol.
