I do think that having a suboptimal relay setup is detrimental to the experience and it makes adoption tricky. I use Nostr everyday and I'm still not sure of how good my relay setup is.
I actually have it on this week's todo list to check what I need to do for ALL my long form Nostr articles to show up in multiple Nostr long form clients. Habla.news picks up some, Yakihonne picks others and blockstack.io gets others but none of them has the complete list.
