For the most part I like how the podcasting environment currently functions, but I do think that Apple's outsized power leads to some frustrating practices. I have found many podcasters who only list an iTunes URL. I rarely if ever use iTunes (as it requires booting my barely-touched Windows VM), and even with it open it is annoying to find the actual RSS address if it is even possible. The interface is so bad that I usually resort to using WireShark or a URL sniffing program to locate the actual feed.
