I watched this video and thought the content was very good however a slight criticism making sure that JW,isms are clearly spelled out for non J.W`s to understand in other words speak in a language that the general public understand because that is who you want to reach and not just J.W.`s.
Also it would come across as more professional if he had on at least a casual or business shirt and not a T-shirt.
presentation means a lot guys , really and to dress sloppy takes away from the message .
Just my 2 cents worth .
