Google+ updated to expand Hangouts audience
Anyway, Google+ has been updated on both iOS and Android, and in addition to allowing teens to create or join Hangouts from mobile devices, the update also allows all mobile users to join Hangouts on Air, which are Hangouts that are being broadcast publicly.
The rest of the app gets a few small changes, but nothing major. There will now be floating timestamps on pictures in photo view, and the ability to report abuse in Events. One small, but really nice change on Android is the addition of shortcuts to more quickly post to G+ from your home screen.
