I would love to exchange promos with anyone who would like to ...I will be happy to play your promos on my show and you can play mine. Good exposure can never hurt!
Any takers? I can upload mine for anyone who wants it.
One of the things I've been doing from time to time is exchanging "bumpers" with other podcasts. Rather than using a generic promo, we exchange clips that are specific to the other podcast.
For example, I recently did one with the "Magical Earth" podcast. They sent me one where they basically said "hi, this is name, name and name from a Magical Earth, and you are listening to Peter Paddon of the Crooked Path." It is a techniquye radio stations use, getting artists they interview to record them and playing them randomly as station identifiers.
They make a great lead-in to a podcast... play the bumper from another podcast, leading into your intro music. They also promote community between the podcasts.
