However, more puzzling results:

Earlier today, filter was not connecting either.
I am trying out nostr.land for a bit. Maybe that sheds some light on all this? I'll report back.

However, more puzzling results:

Coracle will write replies to the inbox relays of those you have tagged in the reply. nostr:npub1jlrs53pkdfjnts29kveljul2sm0actt6n8dxrrzqcersttvcuv3qdjynqn is using relay.damus.io, nos.lol, and hbr.coracle.social as inbox relays. nostr:npub18kzz4lkdtc5n729kvfunxuz287uvu9f64ywhjz43ra482t2y5sks0mx5sz is using creatr.nostr.wine, among others.
Yes, this is what is redundant with filter.nostr.wine, as it also does that. It is its own mailbox implementation.
Interesting. I knew about its blastr relays, but did not know it also uses NIP-65 for replies to post to the inbox relays of those mentioned.
Is this something we should be expecting relays to handle for us, rather than clients?
I think our collective paranoia is negatively affecting UX.
As long as these all-in-one relays do not censor it's a superior solution with less waste.
Censorship incentives are low, they can be swapped immediately for a different provider and affect their brand reputation.
