I think there's a lot of potential here. I think the folks here -- at PipesMagazine.com -- do a pretty good job with their weekly podcast, but for me it really depends on who the guest is each week. (I'm not the least interested in artisan pipemakers; my passion is tobacco.) For me, an interview format would be my strong preference. Unless you're Greg Pease, I'm not sure I want to listen to anyone share only their own opinions about pipes/tobaccos for 30 minutes or so.
There's a ton of really badly done pipe videos on YouTube. I recently went hunting for some tobacco "review" videos and was amazed at how awful they all were. . . unedited, unscripted, meandering, and. . . well, baffling. I saw one where a guy spent a very long minute constantly sniffing an empty can telling us, in various ways, how badly it smelled! (And I hope that wasn't anyone here!)
Finally, I'd much prefer a video podcast than an audio-only one. And it needs to be viewable on an iPad, preferably downloadable through iTunes and the popular podcast downloaders (like Downcast).
And FWIW, I'm a 51-year-old who LOVES technology.
