Just curious - are you using podcasts? Or are you producing a podcast for your patrons or colleagues? Do you use them as audioguides or for PR?
I know there are a lot of libraries in the US who are producing podcasts - is "Open Stacks" still around? - but I wonder how they are used.
(Should I mention that I'm responsible for the Netbib-Podcast, so that I'm kinda obsessed with this "thing"? ;-))
