I just noticed that
- people don’t read my comments as much here as on Lemmy so I get way fewer replies
- someone replied to me and I didn’t see it in my notifications, even after tapping Notifications, so I had to go to the thread where he replied to me, check out all my 10+ comments, and see that one of them had a reply. I saw no other way to find this.
I think comments may be processed as posts so it might be the number 3 but i’m not sure, maybe test it :)
As far as I can tell a comment is a response to a thread. A post is a microblog entry and a reply is a response to a post.
