Well, I looked for ages and although I found plenty of library related podcasts, none of them really captured my interest. many of them are pertaining to particular library services in the US. Which might be OK in some cases but to be honest the amount of stuff out there is a little overwhelming.
Also found some conspiracy theory podcasts and of course, the reason radio will never die - podcasts are the Web 2.0 radio. I found a good one here and subscribed to it with my bloglines account.
