Animated GIFs have adequately been tested and I believe we can all agree they display correctly. To that end, can we please stop posting them? If you need to express your individuality by uploading a hilarious animation created by a 14-year old, please do it on tumblr or "cafeteria" in HipChat.
When I'm agonizing over the alignment and colors of all the pixels, it is really painful to see all these GIFs on repeat. And repeating. And repeating. Forever. Never stopping.
