@sophistifunk I tried it this afternoon but for some reason it didn't really make much sense. I couldn't create a mental model of the interactions. It felt like something a 20yo might understand straight away LOL. Maybe I should stick with it?
@siracusa Listening to the ATP after show reminded me of this post http://www.bakadesuyo.com/2013/10/public-speaking-fear. Being pilloried for verbal blunders is predictable but also a shame. Even the "greatest speakers" in history screwed up constantly.
