Journal columns, you've seen me mention the "Public Radio Exchange"
before; they are a content clearinghouse for independently-produced
programming available to public radio stations as well as individual
listening.
PRX has launched a live stream called "Remix Radio" that provides a
continuous stream of programming from the programming available at
their website.
It strikes me as a "pot luck" opportunity to sample something random
that you might not otherwise check out in your usual "appointment
listening".
It isn't 100% spoken word -- it's more of an "interesting sound"
format...but my impression is that it's primarily spoken word...
