Query: Ranking Cities is a Fool's Task

Unexpected below par book from Lonely Planet. Fair to middling at best! I gave it one star overall. This book's purport to rank world cities is a fool's endeavor. The rankings are totally subjective and are based on opinion. I consider myself a well traveled individual, and unless one has personal knowledge of each city to be ranked, they can not provide a valid ranking of any one city as it compares to all the other ranked cities. Not a valid reference work, a non-scientific amalgamation of mere opinion; to be read by those with too much time on their hands. Thanks.
