In these sites, down-voting has become a passion to prove intelligence. Yesterday, I got two upvoted answers downvoted simultaneously (Someone has down-voted both within 1 min). I think they're too busy in leaving comments and reading Etiquette
Why isn't there a rule: "For Downvoting upvoted posts, comments are must"
The posted users don't know "For which silly reason, they've been downvoted..." Then, how would we correct the answers? Only one choice left out: "Answers must be deleted".
