Looking at the multiple responses, I'd say that there's an overwhelming notion that people want this to happen, but we definitely need a strong foundation to stand on.
First off is the leader, or host (with the most). Pretty much this'll be the guy that has to deal with people, because people come with a lot of stuff (commitment issues for one). As a college student in the theatre/movie scene, I've seen too many examples of where people are initially excited about a great idea, but then fade away... only to leave the leader by him/herself... incredibly frustrated.
Luckily, we have plenty of people who are eager to do this, and it doesn't take as much time/effort/money/etc. as a full blown theatre/movie production.
Next off we need a long term plan. We need to blow past the first podcast with a plethora of ideas. Once again, I've seen too many examples of a great idea that has a great start... and then "now what?" starts to creep up. It can be messy.
But once again, the people speaking are the content, so we don't have to worry about future episodes (aka, future speakers) too much. We just need willing people.
So yeah, I'm definitely up for this idea, I picked "1" a while ago without a second thought, but your epic wall posting skills have brought me back to say "Yes, this is a great idea. And yes, I'm willing to give it all I've got."
Plus, you guys need to have someone like me on this podcast. Sonic must have a voice!
