For the first instant I saw the page, I thought it was one of those spammy, ad-filled domain placeholder pages. It's because the design is similar - boxy, list of links, no images. I'm not sure if that first impression will actually drive people away, but you think it might, you should change the design a little to distinguish your site from those placeholder sites. Perhaps adding a podcast-related image or a large logo to the main page would work.
