This may partially be my fault >_>
I had suggested the idea to Corran a while back, primarily because I wanted to use the functionality for the IC4 tournament, since I had planned on making a lot of video content to help keep the tournament interesting. I had kind of pictured that being the big "debut" of the new feature, but then I never did it, and very few other people even knew the feature was there to begin with.
So, for Corran's sake, start using it! If you're gonna announce your video, put the embed in there.
