The Big G has detailed a few changes that are en route in forthcoming updates to both the Google+
desktop interface, the Android app
and -- with an undisclosed lag -- the iOS app. You and your inner circle will soon be able to attach Hangout
invitations to specific posts, so you can "upgrade the conversation from long-form to live" with a single click. The Hangouts On Air self-broadcasting feature is still in development and only available to selected celebs, but Google is about to roll it out to "hundreds more" public figures and users with large followings, while also adding features that will eventually appeal to normal people's vanity too: including the ability to upload full-length and private recordings of your supposedly charismatic rants to your YouTube account.
