Wow Joze... truly inspirational! Not only do you communicate very well (I couldn't actually tell if you were blocking on purpose), you conquered public speaking, one of the biggest fears of most people who consider themselves 'fluent'.   I noticed you used some techniques such as a quick diaphragm inhale just before speaking and speak with as much expression as possible, all with complete confidence. Would you mind sharing with us how severe of a stutterer you considered yourself before (scale of 1-10, with 10 being almost fully fluent), and some of the other techniques/exercises you utilized to speak as well as you did in front of 2500 people?
