I‘m in the process of trying to get a new podcast off the ground (if you haven’t heard it yet, check out Photo Share Podcast), and part of that means spreading the word to listeners of podcasts, or people who might be interesting in the subject of online photo sharing (like Flickr!). And I want to help users of both iPods and Zunes to hear my podcast. But . . . Microsoft won’t let me contact users of the Zune because I’m a Mac person and can’t install their special podcast submission software (it’s PC only). If you want to submit a podcast to their “marketplace” for consideration you’ll need a PC, thank you.
