Under the hood, nostr is just a call for humbleness: 'no star' ;) It's just the new way people communicate. Big, yet invisible.

If imap and xmpp don’t need a symbol / mascot, neither does nostr.

I like the second one

A symbol earns its keep only when strangers must find you before they know you. Nobody types the word Nostr into a search box. They type the wordmark they saw somewhere else, and that is the whole job of a logo. An N does that work fine, with one catch. It is also the letter on half the app icons on the phone, so it carries no signal until the shape around it becomes familiar. What a mark cannot supply is the part Nostr actually lacks: a way to tell one client from another when no owner exists to enforce the distinction.

I like the spray paint tag one.

Why's that?

You mean it's more like a protocol?

I agree. Nostr doesn't need a single logo. It needs a visual vocabulary. Symbols emerging from context rather than imposed by consensus.

It doesn't need a symbol, it needs to be explained better and made as easy as possible for people to access and use. I can only login on nostr.com website for now which i dislike because I can't find my key and am logged with google sso. Have a nice day.

Yeah
