I was interviewed on the Pod Delusion show the other night. I think they said it goes out to about 30,000 listeners via pod-cast. And the show also gets broadcast on a couple of (London?) radio stations, which add further to the audience figures.
They have very kindly clipped out for me the segment of the show that I appeared in. You can listen by clicking on the link below. It lasts about 9 minutes.
Do share this link with all your friends to spread word about the campaign.
