GIfs are as easy as they're evil. Short animations that would take 400KB, take 4MB and a extra-high-bandwith internet connection to load. This is specially critical on mobile, with limited CPU, limited battery life and limited data plan.

4Chan has supported webm along gif for a while now, and it works perfectly on Chromium and Firefox on Linux. To have a similar experience on Imgur, I need to use the "Imgur to Gfycat" Chromium extension.

It's 2014, let's move on already.
