I’m an iTunes gal, and have subscribed to a number of podcasts over the years. At my height I listened to about 30 podcasts regularly — I’m now down to 2 (The Word Nerds and Grammar Girl).
I think that podcasting is a great way to involve your patrons or audience and keep them engaged in your programming. Recently I attended an author event at the University of Minnesota bookstore. (Lynne Cox. Awesome.) The bookstore extends their services by offering their author lectures in a series of podcasts too. I think it is a great way to involve a larger audience, and to keep those people who came *once* involved. Same goes for the MPR podcasts — smart way to keep your audience involved.
Am I inspired to create a podcast? Personally, no. Professionally, I think it’s important. My library system has made audio versions of booktalks available on our website, and there is a regular podcast created by teens for TeenLinks.
Like blogging, I think it would be important to create a unique voice or angle for yourself if you want to get and keep a regular listening audience.
