The team that designed and built the recent YouTube update will answer your questions in a Hangout on Air Thursday 12/13 at 4pm PT on the YouTube channel . To ask a question, submit it here before Noon PT on Thursday 12/13. If you can’t make that, we’ll also hold a Reddit “Ask me Anything” on Tuesday 12/17 starting at 10am PT to answer your questions.Those of you who use YouTube most have learned the secret to making it even better—find the channels you love and subscribe, subscribe, subscribe. Last year we began to make it easier to subscribe to the channels you care about by introducing a Guide on the home page. When you add subscriptions to your Guide, you organize YouTube around what you like, available whenever you watch YouTube. Today, we’re taking the next step by bringing your subscription-filled Guide with you across both the site and all devices, as your best source of what to watch on YouTube.Just subscribe to your favorite channels and the Guide lets you know when there are new videos waiting for you to enjoy, suggests the latest and greatest channels you might like, and shows you what your friends are sharing across the web. You’ll also find the Guide and your subscriptions on apps across hundreds of millions of devices including Android, iPhone, Playstation 3, Google TV and more.
