The reason we have a podcast
1) People are always waiting to talk
2) People always egotistically think their idea has merit
With the podcast they come to it knowing that they don't get to talk. They just get to listen.
Listening is the first step to understanding. And it does not matter how brilliant you are, you need to know the other side before you can oppose it.
Some amount of information penetrates.
Then hopefully they come to the message boards informed.
