Bart,
I do not give any weight to belt notching, certainly I can appreciate those that have the means and the connections to do it though.
What I do rate very highly are golfers that are passionate about the architecture, who have or are working toward playing their own personal top 10/25/50/100. Because the magazine lists are just that, someone else's list, which may have zero connection to what we may find important. I see no difference in wanting to go to the Lourve to see the Mona Lisa, or Florence to see the statue of David, and wanting to see Cypress Point or Ballybunion or NGLA, OR the Grand Canyon, or Cappadoccia, or the Nile - as really they are all, or should be all about appreciation for fine things, art, nature, special places.
Whether someone else 'ranks' them as the places to be, only serves to highlight what should be on our radar to build our own bucket list if you want....and hopefully along the way (actually you are guaranteed) to meet some amazing people and perhaps even a Kavanagh, and that is what drives me to see great courses, great places and meet new or old friends.
Ultimately, beauty IS in the eye of the beholder, but there are some things that rise above this, and there are some golf courses, designs and architects that can show us an incredible place and an incredible test of golf, this is perhaps what those others don't show us, and why everyone should look to see what is great in golf, and so all power to those that can, or want to see the best of the best.
Luckily we are all different, and that is why a top 100 golf course list has so many flaws, so for me, belt notching is important as long as it is your own belt, and not a magazine's "belt" trying to sell advertising.
