While I love helping others with their podcasts, I also love learning about podcasting as much as I can. Most of what I help clients with is actually a combination of what I've learned over the years from podcasts about podcasting (yes, I know it sounds meta).
One of my favorite things about these podcasts is how I've reached out and talked to all the hosts and consider them all to be friends. You'll also notice that although they're technically "competition," one of the great things about podcasts is there really isn't such a thing. It's not like listeners are forced to choose to listen to one podcast over another -- I can listen to as many shows as I want on my own time.
