podcasting is a relatively cheap way to express your ideas, and it's pretty low overhead. You don't need fancy mikes or video cameras or anything else to get started. One of the tools that we used is called ascript to ediit the pod. That thing is so game changing. It can also allow you to edit a podcast audio similar to how you edit a written piece of content. Tescript is awesome. And i've been really impressed with how easy, or how accessible, it almost makes like professional podcast editing.
