In this question I posted an answer. After I posted my answer (by comparing timestamps), someone else posted the same exact answer I did (albeit with a GIF to illustrate it). It is now voted up higher than my answer (the "original" one).
Is the inclusion of a GIF a good reason to post a duplicate answer to the question? From what I understand in terms of Stack Exchange rules, a minor inclusion like that would have been better posted as an edit to the original answer.
