Having recently been asked to discuss the podcasting potential for a local law firm we've found that there's a definite market out there for it in the legal service... an example from our forward thinking Canadian cousins can be read on www.lawyersweekly.ca just search for ..."Podcasts: way for law firms, lawyers to develop ‘strong bonds’ with listeners" by Luigi Benetton.
In spite of "appropriate attribution" LittleSmasher wasn't allowed to show you any of it here but it was all about how great podcasting is as a tool reach out and form strong bonds with clients and partners.
Worth a read, I'd say.
As long as you read it from the appropriate digital space of course.
