Intelligent, I thought, but yet, just another 'method' that works for some people and circumstances and not others. I agree with Bill that there are so many exceptions that there is no rule; but I also tend to agree that most people who post on the Internet just bang away without much thought for composition, or their compositions are cliches (naked women in creeks or old buildings, aspens in sunlight, cracks in granite in b&w.) They **should** think about it more.
On a different forum, Sean Reid talks about taking street photographs where the "action" is completely spontaneous and accidental, but the "set-up" is carefully thought out, and functions almost like a big sheet backdrop paper in a studio. He's doing both at the same time...
Even in landscape, you have all kinds of (possibly apocryphal) stories of Ansel Adams scambling to save the masterpiece on his last sheet of film in the day's last light; and Galen Rowell said that the most famous shot he ever took (the rainbow over the monastery in Tibet) he got only by sprinting across a field to get the monastery framed behind the rainbow...
I think that the best landscapes are taken by people who have spent a lot of time in that landscape and have thought about it and experienced it, so when the magic moment comes, they recognize what's happening and where exactly the best potential is at, so that, in effect, you've spent a lot of time preparing to do something really quickly. The worst landscapes, IMHO, are taken by people who just visited Blahnikstan (or wherever) for the first and last time in their life...
I spent several years studying Shotokan karate and one of the major points of the training was to make the same movements over and over again, thousands of times, very precisely, but more and more quickly, so that if you were ever compelled to fight somebody, there'd be no thinking involved: you would be so habituated to the possibilities that the reaction would be thoroughly automatic but at the same time, intensely trained. The same concept would be applicable to the best photogaphy, I think.
