I am now a regular commuter to Glasgow. As everyone who knows me will testify, I am a big fan of public transport. It's possible to work and travel. Sitting on a train listening to an interview and making edit notes is a real benefit to a freelance podcaster. But, I also note that I am sitting amongst my audience. Sure, you can hear the percussive beats of Megaflangedeathbunnies from the young guy with long hair and R'n'B classics from the young woman sitting next to you; but there are an awful lot of people of 'certain years' who seem to be listening to something that might be audio books, might be intelligent speech or might even be plain old podcasts. Hugely reassuring when you consider the market this could represent.
