I answered What is the difference between hosts and hosts.deny? with a one-line answer (first line of my answer, basically RTFM).
I got downvoted to -2 for my answer.
I Edited and improved my answer (IMHO).
Will the downvotes go away? Will the downvoters be told I changed my answer?
If the answers are (No, No), why would one update one's own bad answer?
