I'm busy at work and don't have time to write this up, but I read both Stephen Hill's statement on podcasting and Doc Searls' response. I don't think either of these meshes well with what I think. This is something I actually have some insight on, as a very early podcaster and as someone who produced entirely by myself a nationally syndicated show that was on the NPR satellites (but not an NPR production) in the 90's. I'll write up my thoughts when I can, but suffice it to say I have many on these pieces. Watch the skies!
