Among Google's social networking project Google Plus niftiest features is its group videoconferencing app called "Hangouts." The free service supports up to ten simultaneous users and it also attempts to negate the awkwardness that's often associated with coordinating video calls by making the experience more casual and free-flowing as any of your friends can hop into and out of a Hangout at any point, provided you've shared it with them.
Among the other features of the app is a ability to play a YouTube video and talk about with all of your friends at the same time.
YouTube just rolled out a new option that makes it easier to jump into one of these video-sharing sessions: you can now initiate a Hangout directly from a YouTube video's 'Watch' page -- you'll find the option under the 'Share' button -- Just click on the "share" button and in the box opened under -- you will find it on the right side (see the picutre below).
When clicked a browser window will pop up, prompting you to choose which Google+ Circles you'd like to share the Hangout and video with.
This is just the first of what will likely be many more integrations to come for Hangouts -- Google has repeatedly said that the app is built as a platform for enjoying shared experiences with friends.
