I am reminded of a social event years ago associated with a business relationship. The host was wearing a shirt with the logo of a well-known private club. A new course in the area had ascended to the first or second spot in the Texas ranking and I made the huge mistake of making mention. This resulted in a profanity-laced "I don't give a ----- about the -------- ratings", a 10-minute lecture on why his course was better, and an ending with an invitation (not to play his course- I later learned that he mostly plays by himself), but to re-visit the subject after his club spent over $10 Million in renovations. I did play his course after the renovation with two well-known longtime members, and though they too noted politely that the rankings weren't important to them either, they both wondered where the money was spent.
I am not sure how widely the "best new" or "best renovation" lists are read, but I think they are of interest to a lot of people whose clubs are being considered. Certainly there is considerably more interest in knowing who designed the courses and changes than there was many years ago when I began to play golf. Branding might have a lot to do with it, which, unfortunately, doesn't always bode well for the local architects whose abilities are often at least equivalent, and interest and commitment to the area superior.
