OK, some questions about this.
(A) Some instances do or don't federate with Mostr, as described in their "peers" API. For instance, mastodon.social doesn't, but several other npubs I follow are on servers that do.
(B) For instances that DON'T federate with Nostr, aren't they effectively one-way channels? Should there be some kind of profile badge or warning tacked onto their NIP-05 info that "they won't hear what you say" or something like that?
And (C), even for instances that do federate with Mostr, I frequently find that my comment replies just don't show up. In fact, this seems to be the "default" behavior. An example is
nostr:nevent1qvzqqqqqqypzptujz495l5qzjfqrzwr0wyenkzhajaq6qah4cuutcfsr5k6e6eclqyt8wumn8ghj7etyv4hzumn0wd68ytnvv9hxgtcpzemhxue69uhhyetvv9ujumt0wd68ytnsw43z7qgmwaehxw309a68yetwv35kueewwfjkcctewvhxcctwvshsqgqqxywug0jlpeehfy77r4wy7av6ldmx0gkhd57m8hdm42xs46tqk5frq0ly
, which doesn't seem to show up on fosstodon.org, despite the fact that that server federates with Mostr
