After a few months in invite-only beta, Google has announced that their social network Google+ is now available to all and no longer requires invitations. Additionally, the popular "Hangouts" feature has been updated with the ability to screen-share and the ability to name your Hangouts, and is now available on mobile devices as well.
Furthermore, Hangouts on Air is now a possibility, allowing users to make public broadcasts that others can tune in to. The first broadcaster will Black Eyed Peas' William. Finally, there is also improved SMS support, better +mentions and +1'ing comments and one of the big things is that Huddle has now been renamed as Messenger.
