Comments made in a "back-and-forth" interchange with one or more other posters sometimes become redundant. I delete all mine, then post one final comment suggesting the other[s] do likewise.
The problem is after deleting his comments, the other party often feels moved to post another reminder telling me I can now delete my reminder. Which can go on and on...
Is there a convention for posting an "over and out" comment? And might the site support (or be tweaked to support) some way of either searching for only such comments made by yourself, or auto-age them out of the system after some reasonable time?
Or is there already a better way of dealing with the issue? I greatly appreciate the fact that these interchanges can take place at all, because they often lead to better Answers in the end. But if they hang around indefinitely they make EL&U seem more like a forum than an answer bank.
LATER Just to head up the point I've already made in comments. I'm only really concerned about this issue in relation to interchanges in respect of what is, or is hoped to become the top Answer for a 'good' Question. I don't much care about redundant chit-chat on less highly-rated Answers or trivial Questions. But EL&U has plenty of Questions that may well be asked again by many people for years to come.
Hopefully we'll assiduously redirect to the first occurence which will have a widely-accepted Answer, which oftentimes is effectively a 'collaborative effort'. It's potentially distracting for that Answer to contain all the preceding discussions which led to its final form. And in an ideal Answer, all comments should be either irrelevant, or incorporated into the Answer text itself.
