nostr's main benefit is actually about being able to have isolated networks bluesky and other social networks don't make this easy, except garbage like matrix and xmpp which don't enable generalised discussion or any other use case particularly i hope you read this message because most nostr devs don't understand that the whole POINT of nostr is being able to partition it, that's why it's not a distributed system, it's just a protocol
When you say "don't make this easy" you mean the heavy lifting involved on their side? This from one of the atproto leads: "One form of decentralization I could try to emphasize here is independent Lexicons. For example, this blog post is published using whtwnd.com, a blogging platform built on atproto. In theory the Bluesky relay or appview being down should not impact whtwnd (which I believe pulls directly from PDS instances)" https://whtwnd.com/bnewbold.net/entries/Reply%20on%20Bluesky%20and%20Decentralization Seems this WhiteWind is some kind of Yakihonne on atproto. As I understand they will have spun up their own child relay and are using that to pull from a select set of PDS instances to create an isolated network. Very much a guess though, I could be way off.
