@evan @reiver I'm not yet sure if I like the idea of placeholder posts or not, but I do find the idea intriguing

@evan a related interesting question to think about: if Bob's reply is visible to Alice's followers, and Alice later gets a new follower, should Bob's post automatically visible to that new follower too?

@evan this is a tough one. From a theoretical perspective I'd have gone with "Bob's followers" because each post is a post in its own right and the fact that it happens to have a reply on top shoudn't change that. (Which is also how it works today, right?)

But seeing too many fragmented conversations has made me think that in practical terms it's better to have replies "inherit" viewership from the starting post—i.e. Bob's post is visible to Alice's followers
