I spent the better part of the past hour going through various RSS feeds. New York Times, Wired, Salon and other non-blog sites. They all use the link element to point to the item listed in the title element. As they are not blogs, they have no blog permalink, and therefore lacked the guid element (my assumption). Mark Pilgrim’s XML feed – his items lacked a link element. He only has guid elements, which contain (TADA!!) the permalink URLs for his weblog. Case closed?
BTW, Rob, if you read this, I’m not trying to take shots or anything. For me it was just a great excuse to learn a little more about RSS. If I’m mistaken in any of this please let me know. Know that Radio does handle this correctly will make me sleep easier tonight. Why? I have no idea!
