When I recommend deletion of an answer, I am offered the opportunity to leave a canned comment such as "this does not provide an answer to the question" or telling them how to edit their question if they are posting a self-answer that is not an answer, just an update.
- If I choose a comment that is already there, will it be upvoted?
- Is there any other consequence (besides adding a new comment or upvoting an existing one) to making that choice? Is someone gathering metrics, for example?
Often, if I see the comment I want is there, I leave No Comment selected because it's less clicking. I might upvote the existing canned comment or not. But I wonder if I am depriving some Big Data process of the ability to determine what fraction of bad answers are "I'm having this problem, too" or the like. Or is it really just a handy way to leave a comment?
