This site often results in overly long discussions in the comments sections. It would be nice if I could flag one of my own comments (e.g., a comment along the lines of "This discussion has gone on long enough") with a flag along the lines of "This discussion has gone on long enough; it's time to move this discussion to chat".
I would be happier with being able to point the finger at myself as the guilty culprit regarding a long, drawn-out comments discussion as opposed to picking some other user when flagging moderators that a comments discussion has gotten out of hand. This capability might also be useful on other elements of the SE network (e.g., skeptics.SE, but I am sure there are others) where commenting can easily get out of hand.
