C.@feditips Right - thank you. I get the visibility effects.
To confirm, regarding the people who saw the original message (because they followed the author or group or whatever) -- they won't see my reply unless they follow me, they're @-mentioned, or browse the local/federated timelines on an instance that received it because of @-mentions or follows. Correct?
I hoped the in_reply_to_id and in_reply_to_account_id would share it with readers of the original message, but figured not.
