Developing a Plan
First Things First: The Plan
From Beginner’s Guide to Podcast Creation By Kirk McElhearn
Amazingly enough, this first step is the one many podcasters skip: develop a plan. Before you start recording, think about what you want to say, and organize your show accordingly. Make notes, prepare your interviews (if any), and try to improvise as little as possible. While a completely spontaneous show can sound good if you’ve got the knack, the best podcasters prepare their shows in advance and work hard to provide interesting content. (See Kirk's Eight Rules of Effective Podcasting) for some tips on creating good podcasts that people will come back to listen to.) There are thousands of podcasts available today, but it’s easy to pass most of them up because they don’t stand out - figure out your angle, and run with it!
Equipment Needed for Podcasting
Headsets
Please try to bring your own headset or earphones/mic with your for the workshop. We have only a limited supply.
Cheap Coby headsets at Target for $10. Or go with a USB headset for better quality. I use the Logitech Premium USB 350. It goes for about $50 at BestBuy. 
We'll talk more about microphone and headset options in the learning lab.
