The new Twitch app has rolled out on the Xbox One, allowing you to submit and share content, as well as archive videos. To celebrate, Twitch has provided a list of top Xbox One channels, allowing you to stay on top of what people are currently streaming from the console.
Currently, it's basically all Titanfall, some odds and ends like NBA2K and Killer Instinct, and a few streams for Garden Warfare. For those who haven't been following the app update, Microsoft has been working closely with Twitch to add new features over the PS4 version, including archiving and instant stream initiation by way of Kinect ("Xbox broadcast").
Hopefully Sony will add archiving soon to their app!
