I also like the conversational feel. I like seeing people in party mode, seeing several mice on a cluttered desk, seeing two or three monitors, seeing the spontaneous version of how the interviewee would really draw their thoughts on the board in "real
life." It makes me feel like I have visited and imbibed some of the air there.
It would be nice if the videos were indexed, such that I could come back later and pick up where I left off.
