Sounds good David!

My thought is that the podcasts should begin by presenting very easy options for getting into the area of amateur data contribution to astronomy science, rather than an emphasis on constructing observatories, photometry, astrometry, robotics etc etc. The rationale would be that emphasis on the latter would have a very small market, vis technically savvy people with money and time to burn, while the former would have a huge appeal (ie anyone with a telescope and eyes). Once people's imaginations are captured, it's a slippery slope, LOL! The podcasts might lead people through to the more 'technical' opportunities, but it's a fine balance between engaging people and turning them off. I'm not suggesting a lowest-common-denominator approach, more a strategic one.
Just my thoughts, no doubt you've got all this covered anyway. Good luck with it!
