The new podcast features in Blackboard 7.3 are actually part of the Podcast Learning Object from LearningObjects.com . This learning object makes it possible to easily add podcasts to your course and syndicate them to your students using an RSS feed. In English, this means your students can subscribe to the podcasts you make available, whether you create them yourself or download them from someone else. This way, students will be automatically updated with the latest podcast in your course and they can listen/watch them on an iPod, Zune(!), or a computer. Here's a 4 page overview of the podcast tools [PDF]. You may also find these resources useful: A tutorial from Dave Taylor on subscribing to podcasts in iTunes. Create your own Podcast (CNET).
