Google's John Mueller amongst some other Googlers often provide video based Q&A style webmaster support for your SEO and webmaster questions.
In fact, much of what I cover here is based on those videos.
The format of the videos are pretty straight forward, you can submit questions online prior or during the video either video the Q&A feature in Google Hangouts or if you happen to be one of the ten people in the live hangout, you can rudely stop John and then ask your question, which is what I do from time to time.
Often before the video hangout starts, John tries to invite people in who ask to be invited that haven't been to previous hangouts. The issue is, these people rarely show up and then John opens it up to everyone and the regulars are the ones who make it into the hangout.
John is now asking for structured feedback on how to improve these hangouts and you can post your advice at Google+.
Personally, I like the current structure, it works well but I am sure there are always ways to improve it.
I'd love to get your feedback on the format of our Webmaster office hour hangouts! What should we change, what should we keep?
In a magical world where you always get your wish, what would these be like?
