Most people don't because they think they need fancy (aka expensive) equipment, tons of technology, and a sound mixing degree.
They think podcasting is hard.
Basically, they're intimidated by the technology. (And I was, too, before I knew how simple, easy, and FAST it could be!)
Podcasting isn't hard, and it doesn't require expensive equipment or super techie skills. In fact, you might be surprised at how easy and simple it is to get a podcast up and running. I can help you!
