I made a couple of responses in a thread, and there was a suggestion that it was easier for readers if these were combined. It would not be easier for readers if responses were threaded, (i.e., effectively, sub-threads are created for responses. My blog allows 10 levels of subthreading.) But that led me to notice that there is no subthreading. This is deficient for a discussion forum. Responses to a particular comment are not displayed with that comment, but at the bottom. If the concern is for the reader, the implementation doesn’t show it.
As well, the suggestion then effectively, if I follow it, would cause me to postpone a specific response, increasing work for me, as a writer. II don’t know what software is being used here and what options exist. It might be a user option to display comments as threads or linearly by date, but I don’t see that.
