A couple of new (to me) public relays that I'm using:

wss://nostr21.com - operated by #[0] running strfry v74. Fast pleb relay.

wss://nostr.foundrydigital.com - operated by #[1] running strfry v92. Based corpo relay run by a dev on the bleeding edge. love it.

Kinda interesting to take a stroll through nostr.watch right now. There's a lot of relays, but few of them are kept up to date. Lots have missing or invalid nip-11 data.
