The idea as I understand it is one part decentralization/censorship resistance so if one relay takes action against you don't disappear, and one part failover so if one relay goes down you can still post to the other relays you are connected to.
TY…
I was entertaining various scenarios, but didn’t think of this .. I thought it was the whole point of Nostr?
There's some concern that people are only using either a client default relays or just 2 or 3 of the most popular relays. I could be way off on this though.
