A major factor in providing entertainment is knowing how it will get to the audience. This week we have Rob Greenlee from Zune Marketplace to talk to us about the impact of podcast aggregation. Rob has seen podcasts die and thrive in his platform and he has expert advice to give to aspiring podcasters. Visit Rob on his blog for more great insight, and leave us a comment on Earwolf telling us how YOU get our podcasts. RSS, iTunes, Zune, directly from our site? We can't wait to hear your answers.
