I STRONGLY dislike this practice. Seeing this canker sore on a post ...
... honestly makes me ashamed to be associated with this site.
I understand what the concern is, and I am sympathetic, but
comments should be sufficient for now to explain why the answer needs updating. This is quite literally WHAT COMMENTS ARE FOR.
this is abusive of editing privileges, because it does not IMPROVE the post, which is the entire POINT of editing. Even more so since it's being paired with an inexplicable conversion to community wiki and even worse, performed by moderators, which blesses such activities in the eyes of users.
if the answer needs work, use editing to whip it into shape as an answer -- not by adding crazy, passive-aggressive little notes at the top.
if it's really bad, just have the guts to delete it entirely! I support this!
This is absolutely not the way forward. These "messages" are an abuse of editing privileges, and are causing material harm to the experience of this site.
edit: these messages have been removed. Again, I UNDERSTAND WHAT THE PROBLEM IS, but this technique is absolutely not the way to accomplish that goal. It sets a terrible example for
the community in that it demonstrates using editing to insert moderator editorial metadata about the post.
If you'd like to open a feature-request to request the ability to add moderator metadata on a post, including some kind of announcement, that is absolutely fine.
edit: this is now complete!
