In this episode, Coach asks, "Why do you post on social media?" both personally and as a teacher.  He offers ideas that he has implemented on his personal accounts that hopefully will bring rationality & civility to his discussions (while admitting he hasn't always been perfect) including why its a GOOD thing to unfriend and block people.  As a teacher, he shares how Twitter has helped him both improve in his craft and allowed his student's parents a window into what is happening in his classroom.
