I like to listen to podcasts on my commute. This got me thinking about how many of NPR's weekly shows would lend themselves nicely to the podcast format. The first show I thought of, though, is Fiona Ritchie's Thistle & Shamrock. It's not carried locally and, unless I find a live stream, I'm out of luck.
Providing the whole show via podcast would work nicely. Broadcast the show intact. You can increase your viewership significantly with minimal increased coast. There's great power in allowing timeshifting.
I think it'd be a great win for NPR. You?
