According to lightningnetwork.plus/nostr_nodes
There are 453 lightning node operators on Nostr.
This is literally one of the main reasons nostr:npub1hxfkcs9gvtm49702rmwn2aeuvhkd2w6f0svm4sl84g8glhzx5u9srk5p6t exists - to help noderunners find trusted peers they can communicate with.

We had more than 300 in the community up until nostr:npub19tcpurtt6xulhw0r6sc404j9jraj0h8me2lzs7z2tqewz7l0hpas59nlea purged a lot of the inactive ones. If you know of any that should be in it, help recruit them. 😀
