One of the recurring things on the main site is comments about the content of a question or an answer.
Once the question/answer is edited to reflect these comments, they are often rendered obsolete. When this happens, I've understood that one should feel free to flag the comments as such.
Now my question pertains to the procedure to follow in flagging such comments:
Suppose there is a string of comments (usually between the first commenter and OP) that is rendered obsolete by an edit.
Should one flag all comments for obsolescence, or will it suffice to flag only the top one, trusting that the reviewers of this queue (not sure if these are only moderators) will read the relevant thread and take care of the other obsolete comments in one sweep?
Until now, I have usually flagged only the top comments of such strings, thinking that it may be better to have only one flag for what is essentially one issue.
I would like to receive some input on this by the comment flag reviewers.
