Hangouts, which let you video-chat with up to nine other people, are arguably the feature that Google+ users like the most about the social network. In addition to getting a group of friends or business associates together on screen, you can join Hangouts with strangers who share your hobbies or interests.
And Hangouts got even better when Google+ revealed live Hangouts On Air in May. With this feature, you can broadcast the live Hangout video publicly from a Google+ stream or a YouTube channel, or embed it on a website.
During the automatically recorded session, you can see how many people are watching. When you end the Hangout, Google uploads the recorded video to your YouTube channel, as well as on Google+. It’s great for musicians, business professionals, or anyone else who wants to try to make a message go viral.
Additionally, the Google+ app for the iPad finally showed up in July, so the millions of people sporting Apple’s popular tablet can now get in on the Hangout action.
