For #nostr #developers how do you decide which relay URL to use? I have a system that transmits notes to multiple relays, but for things like reposts (NIP-18) struggling to decide how to determine which relay URL to use for that.

Obviously choosing an unreliable relay or a relay that eventually goes offline isn't a good practice. And it doesn't look like there is a way to define multiple relay URLs.

What do you all do for this?
