let’s say A makes a thread, B posts something in that thread and C makes a reply to B’s post.
if C’s post is right after B’s without any comments in between it doesn’t show that C’s post is in reply to B’s post.
(here my post was in reply to Chippunk’s but it doesn’t show that it is)
I assume the reason for this design is that ‘it doesn’t need to indicate that it’s in a reply to the first post, because the reply is right after the post.’ but the problem is in some circumstances other people wouldn’t know if its a reply to the OP or B’s post. especially if OP and B agree with each other and C is trying to argue with B. it can be avoided with quotes but its just bad design imo.
