One advantage of threaded comments is that the exchange isn't in anybody's way. If User A posts, User B comments, User A says "thanks, fixed", and nothing else happens, no harm done. If that's the entire thread, either of them could flag a comment and say that the entire thread is now obsolete. Comment threads under a post are shown in order by last-update time, so newer threads will push the "dead" one down and eventually out of (default) view. Comment noise isn't as much of a problem on Codidact as it is on Stack Exchange because comments aren't a single list of top-level comments under a post. Feel free to clean up, flag, or ignore stale threads. If there are a *lot* of comments or comment threads on a post and the obsolete ones are getting in the way, please flag to let someone know. Mostly we don't expect this to be a problem because of the way we designed comment threads.
