I am fascinated by the inputs to, machinations of, and outputs from the global financial system. That's why I love this kind of behind the scenes, in depth coverage of something as arcane as LIBOR. (Well, I guess its not arcane in this world, but among "normal" people, a group I've never been accused of belonging to, it is.) It gives you a sense of what really goes on in calculating LIBOR, dollar LIBOR in particular. And FINALLY, an explanation of "eurodollar"! Very cool indeed.
