A ton of new updates
Google has just pushed out a slew of huge new updates to Google+. They include:
No more invitations. Anyone 18+ is free to join.
New Hangouts. Now with screen sharing, Doc sharing and more.
Hangouts can be broadcast. Go "on air" with your handout, and others can watch even if it's too full for them to access.
Mobile hangouts. Android devices with front-facing cameras can join hangouts now; and they work very well!
Huddle is now called "Messenger". In addition, you can share photos through it now.
Search! You can finally search Google+.
More is coming, but those are some sweet features. Full details on the Official Google Blog. What's your favorite new addition?
