When should you delete your own answers? I'm not asking for only the case where your answer is wrong (which is discussed in this topic), but more generally, when it would be good practice to delete your own answers.
For example, consider the case where you have posted a correct answer, but there is another answer which is entirely similar and gained way more upvotes or has already been accepted. Would it be good to delete your answer then? On the one hand it would cause less clutter, but I'm not sure if deleting a correct answer is standard practice here.
