Additionally Aaron Parecki had some thoughts a while back on his microcast (episode 9: Streamlining My Microcast Workflow) about improving his production workflow. Earlier today he also created a discovery website (with subtle hints of a webring) that acts as a discovery mechanism and network of sorts for microcasts which you might find interesting in light of your plans.
I might also submit that if you’re doing it for students, starting with small, short microcasts are always a quick way to get started.
All this to remind me that I just got a Yeti Blue for my birthday and I need to fire it up to continue on with both my microcast and my longer format podcast.
