First of all, it's horrible because lethal and lifechanging injuries happen on the hill every day, and this could be one of them.
Second, nobody is getting "pwned". Just like someone way up there ^^ said, he might be better than all of us. Heck, he might even be a damn good skier who's just trying snowboarding. And snowboarders in general are just as "cool" as skiers, so no snowboard-hating.
Finally, I admit that it does look quite funny how he floats in the air, out cold but still steezin' it.
