Having browsed the welcome relay for a bit, I think content -finding is of major interest (and not just to noobs lol), not specifically re: relays but it's interesting that there is a desire to seek. I was saying this earlier somewhere also that part of the joy of nostr is finding and digging for content.
I am also under the impression (might be wrong, I don't know much) that it is possible that private relays already exist but wouldn't necessarily be known. Which is curious to me.
