Mario Kart 8 is out today, and Nintendo is stepping up its social hooks with built-in sharing features. The "Mario Kart TV" feature lets you share and view highlight reels, and if you don't have a copy of the game, you can now view them through a dedicated site.

The Mario Kart TV site lets you sign in with your Nintendo ID, cycle through some of the popular current videos, share to social networks, and even switch to the YouTube versions if you'd like. It makes for an easy way to find a pretty massive number of gameplay clips, just in case the various trailers haven't done it for you.
