Perhaps there's something different about these podcasts, but my gut reaction reading this article was that you could substitute "podcast" with "cable news" and it would mostly hold up. The difference, I suppose, is that most of these podcasts are narrower niches and "deeper" ie. longer stories within their niches than the "soundbite" versions of things that you get on TV, but, unfortunately, poorly reporting history has been a popular pastime for as long as there's been media.
