In an episode of Blog Talk Radio’s Marketing Club, host Chitra Agrawal interviewed Cyrus Webb of Conversations Live on how to create, host, and promote a successful author podcast. Sadly, this audio is no longer available.
You might want to listen to this Conversations Live interview with author M J Rose. Note there is a long silent minute when they go to commercial, but the interview continues after that.
