The ABC has a great range of podcasts, but I think theirs are so strong because their medium is radio and it fits podcast format well. The British Library's podcasts weren't so interesting as so much of their focus is the written word which doesn't translate so well to a podcast, or it's adapted from a seminar or presentation and so all the visuals are lost in the podcast.
Podcasts have great potential though and I have downloaded ABC ones before where I've missed a program. Don't know if there are library applications for podcasts, perhaps radio interviews that OMB staff frequently give could be podcast, although in those instances people would go straight to the radio website to podcast, rather than the Library.
