I have participated in a number of webinars where there was a similar format: set presentation followed by audience questions and clarifications. It works well, because every audience is different, especially in this broad field of online community.
I am grateful to Hugi for having something for people to follow while we got the tech and time issues worked out. It isn’t something we would do otherwise. And he was a fine addition to our duo of Noemi and myself, making many excellent points.
The hosting where you don’t see the live audience is similar to radio. A certain kind of performance art.
