I like that idea, almost like a prioritized queue of content - show me the stuff I'm sure to want to see first, and then just gimme whatever. In the context of NPR, the "stuff I'm sure to want to see" is probably just "the news." But maybe other platforms / distribution channels would have a more specific notion of what deserves my attention first.

I guess this is basically how TV worked in the pre-streaming days - the new episode of whatever hot series aired during the prime time slot, and lesser slots were filled with reruns / resyndicated stuff.
