I read the posts about how the only replies you see to remote posts are the ones from people who are followed by other people in your instance.
That makes sense. Those replies are already cached on your server, because replies are really just versions of posts.
I understand the reasoning, even if I think it’s problematic. On the one hand, it means you aren’t likely to see spam and troll replies. On the other, it can make the OP see a mess of redundant, unintentional “me too” replies.
But it raises some other questions I haven’t seen answered.
1. What happens if I reply (as is recommended by many) with a reply that is “limited”. That means that my reply does not appear in the public stream. So it sounds to me like it will only be seen by the OP, anyone I tag, and (is this true, or not?) by other people in the OP’s instance who open the post to see replies. It won’t be seen, even when opening the post, by other people who follow me. Correct?
2. It’s a cache. It has a TTL. Does that mean that on old posts you won’t see replies except from people on your instance? (I’m assuming *those* post-replies don’t expire.)
