I don't give much credence to the the rankings or even the methodology since this  stuff is mostly subjective,  but for a general overview of a wide range of fields with just enough information to get a sense of how each job fits into the larger context of the world, it provides some interesting insights--especially in  how the five categories factor into the way that each job has been ranked.  Check it out yourself if I've intrigued you...or just proceed  to...
