The ability to host a silent webm and then link to either gif version or webm version is something you find negative?

My only annoyance there is that sometimes the embed bugs out a bit, but that's mostly firefox's fault.

No, the fact that they put it as if it was their invention, and the fact that linking imgur.com/XXX.webm redirects to script-ridden ".gifv" nonsense is what I find annoying.

Bugs out extremely often on mobile chrome.
