The Xbox One's brand new, full featured Reddit app, ReddX, has been released and is now available to download from the Xbox One store.
Created by the Seattle-based Stern Beast, ReddX allows Xbox One owners to bring the addictive (sometimes scary) content of Reddit to your television with full input support, full snap support, Achievements, enhanced image and album support, YouTube support, and enhanced animated GIF support. There's even upvoting and downvoting.
Reddx is available for free for both Gold and Silver Xbox LIVE members in the U.S. and Canada; you will have to put up with an ad every now and then, however. Stern Beast is looking to bring the app to other countries, but unfortunately their ad provider only serves ads in U.S. and Canada right now.
Of course, since Reddit is known for its "very diverse community," there is some content that can be deemed unsafe for minors. For that reason, ReddX is rated 18+ and requires that the user be able to see User Generated Content. Stern Beast is exploring ways to utilize the NSFW tags.
I'll just recommend staying away from /r/spacedi*ks.
