It’s an easy choice once you’ve had a few relays, but a difficult one for new users who just want something to just work. Apparently Nostr doesn’t just work. “Am I making a mistake if I choose this relay or another?” Turns out you could make a mistake! But also not a terrible one.
Not giving new users some random defaults for complicated settings and mechanics and not telling them they can just change them later is just bad UX.
Every single on-boarding step a user must make is a potential cliff.
