I have just been going crazy listening to podcasts since I discovered downloading them to my computer and listening whenever I am home alone. I listen to Flylady and all her friends; I listen to Jonathan Roche for moral support on exercising; I listen to several knitting podcasts, several environmental ones, and just today I discovered a couple of quilting podcasts. A whole new world.
It has definitely cut into my NPR listening time though. I only get to listen to the radio when I am home alone anyway, so with the podcasts taking up that time I only hear news when I am in the car-again, alone.
