I didn't care about Podcasting *until* I realized the time-shifting ability for regular broadcasting. I started using a online radio recorder to "tape" my favorite NPR shows for listening at another time.
Now a few stations like KCRW Santa Monica and WNYC New York are providing wonderful shows like "On the Media" and "Left Right and Center" as Podcasts. Sure it is just an experiment in the Latest and Greatest Tech but I'm already finding it extremely useful and I hope others do to (and decide to pledge to these great public radio stations!)
