Google+ On Air is a fantastic tool to interact with your customers, and todays announcement makes it even better. Now you can:
- Solicit questions from up to a million concurrent viewers
- Select and answer questions live
- Timestamp the YouTube recording by marking questions as you answer them
If instead you're watching the Hangout On Air, you'll now be able to ask and vote on questions live, as well as replay the Q&A even after the broadcast is over.
