It is a "goal" in the sense that the goal is to reach and start the discussions with as many people with open minds that will hear.
It is not a goal to gain any level of "fame" or "infamy", just that, I know that it is easier to get people to engage in a few minutes clip than it is to capture an audience in text.
The hold back is more that it is also easier to scrutinize my mug, my accent, and each "um", "err", a near cuss word. Where in text, as long as it's generally written to be understandable, I am satisfied.
