I can't stop thinking about "relay injection".

Scenario:

- I have 4 relays I write to and read from and this forms my overall nostr feed both globally and locally.

- A conference in, say, Amsterdam (call it AmConf) starts up and a nostrich launches a relay just for that conference that I can read from but NOT write to. Only conference attendees/staff etc. can write to that relay.

- I delete one of my 4 existing relays and subscribe to the AmConf relay.

- My entire experience is "re-flavored" because 25% of my relay intake (read) is now from a completely different AND fully themed source (most notes are going to be about the conference since what I'm getting from that relay can only be written by people attending the AmConf).

Am I just getting this whole thing wrong? If I am not then nostr is doing something natively (read this as an 'emergent property') that nothing else does. I started thinking that I should have seen this property in the Fediverse but I never noticed it there. Maybe because most servers are longer lived than nostrasia.nostr1.com (the #nostrasia relay that will be going away now that the unconference is over).

Maybe I'm reading way more into this than I should but I don't think so. I think this is an obscenely overlooked emergent property that adds a vibrancy to the experience that nothing else can. Unless, of course, I have this whole thing wrong and if I do I hope someone tells me.
