Can someone explain nostr telays or point me in the right direction to learn more. I am connected to some 13 relays on primal. I don't know if that is necessary. Sometimes when I go on Amethyst there are things there that I don't see on primal. I just tried out some other clients and they were wanting me to connect to write relays. Seriously, how am I supposed to know which relay is a write relay? This all seems a bit over whelming.
