For this thing I chose to go to Minnesota Public Radio's podcast. There's so much stuff to listen to and it can be fun. I listened to the song of the day and if you want to listen to it too here the link:

It was simple and organized very nicely making it easy to navigate through the website.
I don't think I would do a podcast on my own personally because I don't think I have a very good radio voice and I prefer having people read my work instead of listening to it.
If Walt Whitman was alive today I think he totally would have a podcast. It would be all sophisticated and called "The Works of Walt Whitman" Not too clever but it gets the job done.
Im not sure if his parents would listen to it but they better just to be supportive!
