I proposed an edit to an answer, and it was rejected. The reason given was: "This edit was intended to address the author of the post and makes no sense as an edit. It should have been written as a comment or an answer."
I suggested the edit to the top-voted answer for a few reasons:
The answer was already well-written and covered most of the likely scenarios. It didn't seem appropriate to add a different answer when 90% of the answer would have been the same content.
A comment would not have been as visible, easily discoverable, or appropriately legible to most readers, especially given that my suggested edit had some code-formatted text.
When I searched for the problem I was having, the referenced question was the first hit on Google. Putting the information that actually solved my issue (which was very close to the accepted answer, but needed one additional step) in the answer seemed like it would help the most people and require the least amount of effort for future users seeking help.
Is adding a separate answer (or a daisy chain of comments) really the best approach here?
