I have always been a fan of Don Norman ever since I read his book The Pschology of Everyday Things. This article on which algorithm works best for the dispersal of toilet paper is marvellous.
I really like the idea of having such a wide range of feeds available, but you have to use RSS 1.0 for it to work with Radio, their RSS 0.91 is broken, as it does not include the <language /> tag.
