I think having a logo for nostr would be nice. Mastodon has one and it’s recognizable. It helps with forming a vision around nostr.

It also makes it easier for people to include it on their website without experiencing choice paralysis.

HTML has a logo, php has a logo. I think it’s fine to have one.

I looked at one website with share button generator for Mastodon (without logos) and it looks incredibly dull. I don’t know about you but I like to feel excitement about something I’m going to try.
