Hi Dave I enjoyed the show about the history and workings of hpr. I did a slot about HPR at Manchester Barcamp last year and during the talk likened HPR to a BarCamp of the airwaves as just like a BarCamp as long as it's legal and you make it clear if familly frendly or not, you can talk on any topic that you have a passion for and you want to share with the listeners. Maybe that could be a new tag line, HPR the BarCamp of the podcast World!!
