Presently a comment discussion has to go on for some time before the system encourages commentators continue it in a chat room.
But feature-requests to allow this before that heuristic makes the offer; as well as to preserve and associate that chat with the post in question, have been consistently ignored or declined. E.g.,
- Should "move-to-chat" be provided on demand (as a button perhaps)?
- Insert a "Let us continue this discussion in chat" comment before thread gets messy
- Create comment-spawned chatrooms for the post, not for the users
- Avoid breaking the "let us continue this discussion in chat" links
So what is the desired practice when a protracted discussion relating to a post is expected?
Is the "move-to-chat" prompt actually a poorly-described "get a room" feature? If so, then should well-intentioned users just continue the discussion in comments so long as it is on-topic? If not then shouldn't a bunch of the aforementioned feature-requests be implemented?
