Through YouTube, Google+ users can now start a Google+ Hangout from a YouTube video so that they can all watch the video together while communicating at the same time. Just click “Share” and then click the link under “Watch with your friends.” Perfect for videos that you want to watch with all your friends as though you were together in the same room. Of course, you and your friends will need a Google+ account first. Head over to YouTube.com now to try it out.
