This should be an interesting way for us in the peanut gallery to learn more about the writers. I'd suggest a few things:
1) Dan is awesome at this, but Bob is not - I would ask that the hosts remain very very neutral this week during the debate. Do not offer opinions on the mag wars. Otherwise it'll quickly become a 2 on 1, as Bob and Team FLEX take on MD. (See: Lee priest radio piece) If Bob can - even just this week - step back and just ask awesome questions, and each side receives equal time to respond, it'd be awesome, and it'd be true journalism!
2) Now, for Bob himself, I'd like to ask him to tell us this:
Please tell us the difference between 2 Bbing mags and 2 Bbing federations. Please tell us why it's A-okay for the sport to have two magazines, but two federations is very bad for the sport. Why is it cool to divide up the BBing audience into segments for marketing publications, but dividing up the federations (mass=ifbb and aesthetics=pdi) is a terrible idea you've argued so vehemently against?
3) Finally, at the end, I would design a structure and earmark 3 minutes so that each guest can hae 20 seconds to make ONE statement which summarizes his points and positions. Tell them ahead of time so they can write it down. The radio show is awesome but closure is sometimes a little awkward. i'd like to hear each person have EXACTLY 20 seconds to share his composed thoughts with the listeners so that we walk away with the impression of a series of thinking points, not 6 guys yelling over each other as we run out of time.
