>Well you are just copying from my kind 0 when my kind 0 updates. And that is a lot of copying and republishing overhead.

Yes, but its not really more overhead than the original NIP-02 spec had (besides p tag relays being more than one), if you don't want the relays in kind 3 p tags to rot you have to update them frequently, it solves the bootstrapping as well.

> And yet you still have to find my kind 0 to do that, which was the original problem.

Yes, but it's much less likely I will fail to be able to now that I know that your p tag in my kind 3 will very likely have at least one valid relay.

> Unless you are saying that you would look into a bunch of other people's kind 3 lists to see if any of them know where I have moved to.  

Yes, if you can't find a valid relay that has my kind 0 or 10002 from my p tag in your kind 3, then try from one of my followers' kind 3, move on to the next one and check relays you didn't see before and so on, that is of course in the event that your list of my relays has rotted into oblivion, it's a last resort. If you *never* find a valid relay that has my kind 0 or 10002 then the network is almost certainly completely split somehow.

> So what you are doing is creating a bunch of redundancy of my kind 0 information distributed all around the place.  We could achieve the same thing more simply by just having relays copy/push people's kind 0 (or 10002) information to all the other relays they know about once they first discover a new version... a kind of relay-to-relay propagation... or even have clients blastr the thing in the same way.

But there's no method to that, you just hope the network is not fragmented, that approach is less robust, and youre burdening relays that have nothing to do with the people involved, hoping they won't just drop these events. It seems to me that this is way more duplication overhead because even relays that don't care otherwise still have to be trusted to participate in storing and relaying kind 10002 events for (I don't know how much) less robustness. This way, you only publish your kind 0 or 10002 to your relays, no blastring required. Just changing the kind 3 p tags to have multiple relays would make this work, everything else is just client behavior, if you use kind 10002 instead of changing kind 0 to have that information inside, although that seems maybe like a slightly better idea.

Anyway I just like chewing on ideas, it seems like a good idea to me and seems more robust and "correct". I don't expect it to be implemented and I'm not picking fights in the nostr world shouting about how everything should be done my way, but it's fun to think about different ways to solve different problems and ponder on how a protocol could work differently and how those differences might make things better and/or worse on different ways. Maybe you're right, maybe blasting your 10002 is practically always sufficient, isn't that much of a bother to relays who already are tasked with relaying messages from every direction, maybe it's highly improbable that the network will fragment enough to make it a concern that needs to be addressed more elegantly, maybe the bootstrapping issue isn't really much of a centralizing force at all.
