YouTube adds new social features to let vloggers and fans connect

The main component is a new Community tab that appears on every YouTube channel. This basically functions as a News Feed for that particular video creator, letting them post text updates, live videos, GIFS, images, and more to their subscribers. The posts will show up in fans’ Subscription feeds, or they can opt-in to get a notification when there’s a new post. – James Vincent, The Verge
