For those of you with iTunes, I highly recommend checking out some of NPR's podcasts. NPR offers a lot of these. You can browse them now, or subscribe through the Apple Music Store in iTunes.
Currently, I'm listening to today's NPR Story of the Day podcast about hunger among the working poor in Smyth Country, Virginia. Sadly, I'm familiar with many parts of this story. I never wanted growing up, but I remember food drives, especially around the holidays, and my Dad working for the Hunters for the Hungry.
To totally change a depressing subject, NPR's all song's considered is also very good.
