Some small improvements would be needed in the future. Like +Sheryl Loch suggested, HOA would be a great idea. I have tried to join the Hangout but it was all seated and later it was off ;-) Maybe if a question has been answered by +Google+ Help the participant may have to be shown the door to make the seats available :-) 10 seats with 3-6 pro's for answering questions or just listening are a bit too less in this scenario.
