I have this podcast queue a mile long on my PDA/media player/phone/whatever-of-the-moment that I randomly pick stuff out of when I don't feel like reading the news in the mornings and evenings while commuting, like I guess many people do. I also have somewhat of an interest in effective communication inside organizations - a skill in which I suck badly, but still would like to improve on. This morning, those two things happened to coincide as I picked out an episode of Podcast Academy with Shel Holtz, recorded a year ago.
An hour long, it's certainly worth a listen to, although I'm not necessarily really convinced about the podcast-as-an-internal-medium thing he's proposing in this speech, at least not in the size of organizations I like to work in. Aside from that, it's a good reminder about what employee communication should be all about, regardless of the medium; that is, to build trust, involve the people, connect with their role and connect them with the customers. It's sad how often those simple principles are forgotten in the grind of everyday.
If you are more convinced that it might be the tool for you, he has some basic tips on how to go about doing that, as well.
The guy naturally has his blog and a podcast as well, should you care to learn more.
