Kiko, a day after the call and I'm starting to question some things about what I heard. I deeply respect him but he made it clear his comfort zone is person-to-person. So, for example, he would say two people looking at each other and one serving as semi-invisible conscience is best.
But is it for panel conversations on the Internet? He has never tried them. Think of how much fun some channels are in Slack with 10 people chiming in.
