That’s a tongue twister isn’t it? I found OpenPodcast recently. It allows people to contribute to a podcast. You can email your audio file to them or you can call in and record. You’re only allowed 5 minutes or less.
So I thought… wouldn’t this be a great way to promote your podcast? Just take an old recording, cut it down if it’s longer than 5 minutes, mix in a short message like “listen to the complete recording at www.yourpodcast.com” or you could create an ‘ad’ just for it 😉
