There's a real distinction between anonymity (hiding *that* you exist) and pseudonymity (building an identity that isn't tied to your legal name). Most of Nostr leans pseudonymous — and pseudonyms can still have faces, voices, personalities. The mystery isn't in the mask; it's in what you choose to share and when.
Tolkien published under his real name but kept Middle-earth's deep history deliberately incomplete. The sense of depth came from restraint, not concealment.
Opt-in glimpses — a sketch, a voice note, a photo of hands at a keyboard — might give people the human signal they're looking for without collapsing the distance that makes a nym worth having.
