http://www.youtube.com/leanbackSign into your account and try this. It suggests videos based on your favorites and subscriptions.
You use the arrow keys and the enter key to use this, it's pretty cool.
From the blog about it:
"A click here, a search there, a browse on this page -- sometimes it can take more than a few flicks of the wrist and finger taps to get your daily dose of video. Luckily, YouTube Leanback wants you to conserve your energy for actually watching more videos. Mmm...more videos...
Just as its name implies, YouTube Leanback is all about letting you sit back, relax and be entertained. Videos tailored to your interests play as soon as you visit the site and they play in full screen and high definition, continuously. There’s no need to click, search, or browse, unless you want to, of course. Watching YouTube becomes as easy as watching TV.
To see what we mean, go to
www.youtube.com/leanback, and you’ll note that a selection of videos -- your “feed” -- plays immediately. This feed is based on your YouTube settings and preferences, including content from your subscriptions and videos your friends are sharing on Facebook (assuming you’ve connected your YouTube account to your Facebook account). You can also watch the most popular comedy, entertainment, news, or more. And if you don’t care for the video that’s playing, use the right arrow key on your keyboard to skip ahead to the next video, or try the up/down arrows to search, access player controls, and browse channels and videos. You won’t need your mouse for this experience."
tl;dr just read the first paragraph, it's short. sums it up well.
HOW TO GET FULL VIEWING EXPERIENCE OUT OF THIS:
Try searching for something. It's fast and easy. I searched "blockland" and many videos were available to me at (quite literally) my fingertips!
