@Brian. I hope you saw the wink ;) at the end of my whine about interruptions. It's a tough balance I'm sure. It's nice when you bring relevant stuff from the chat stream into the lecture, and when you keep the chat stream on track with Questions relevant to the lecture. Max's timing through the slides feels pretty good to me; it's just not a lot of time, but that's not a bad thing either. Thx to both of you.
