Oops. Ok, so on the one hand I like using relative URLs, with in the back of my mind the idea that it means you can just take the entire site and dump it somewhere else, and the links will still work. On the other hand that means that RSS/Atom feeds contain links that make no sense out of context.
So for those of you that read it that way, here’s the link to the iTunes Signature one more time, this time with an absolute URL.
Now that that’s taken care of, I think it would be nice if WordPress took care of fixing the links for me, but I can’t be bothered to see if there’s a nice plugin or hack I can apply.
