While in the Review interface this morning, I ran across this question. I started to flag the answer as Other/"just a link" when I noticed the long string of comments.
I thought I remembered a discussion here suggesting that users should edit posts when they can, and only flag moderators if necessary (to resolve disputes, close/delete questions, answers, or comments). Bearing that in mind, I suggested this edit, which was summarily rejected.
I personally feel that the information in the comments is worth preserving, and mentioned that in the suggested edit -- as it stands, the answer is terrible. If the edit had been approved, I would have submitted a flag to have the comments deleted as obsolete. Should I just have flagged a moderator and made a note about this?
