Once you get past conditioning (i.e. firm, dry, fast) the biggest single factor in my perception of a good golf course is the way various ground contours tie together to create the actual play of the ball on each hole. I think that sort of thing is extremely difficult to capture in pictures and even written descriptions often don't do justice.
So it's natural that a forum on the internet, especially one that describes courses all over the world, will end up creating an emphasis on thing you can see. Frilly edged bunkers, rough lines, trees, macro contours of the green complexes, tee boxes. Some of the most important elements of a course like RW&N we almost have to take on faith when someone who has played there tells us it plays wonderfully.
But any armchair critic (or supporter) of a course can bang on about whether the bunkers ought to be faced differently or if some tree or another ought to be cut down.
