I couldn't agree more: I try to tailor the tone and content to the audience, as much as possible. See for example, my appearance on Bloomberg and even Max Keiser, where I am facing a general audience and I offer a perspective focused on technology innovation, security innovation and growth opportunity for a new industry.
In the Vegas case however, I had 500 people in the audience who had spent 2 days listening to the entrepreneurs talk money. Which is fine and necessary, but I felt that a different PoV should also be voiced, on the last day, on the last panel. So I tailored my content and tone to my audience: the 500 people who came with passion for bitcoin, not my four (very gracious and patient) co-panelists. Not my best work, or my proudest moment as a panelist.
I do dozens of interviews per week and appear before a variety of audiences several times a week too. Some of those come out well, but not all. Sometimes I miss the mark on my audience. Not everyone cares for what I have to say, but I speak from the heart and I'm always open to changing my mind and my tone as I learn.
Thank you for the honest feedback.
