I also think clients should have easy toggles for switching between comment sections by niche relays ("ok, I see what this guy's bitcoiner friends are saying, now let me see what his enemies monero guys are saying about the same thing by connecting to the set of monero-loving relays") and other stuff. Nostr is still too small for these cool thing to be viable though (and also too small for people to be banned too much), but I think we'll get there.
