I am not surprised at all. For many years I was very much into hi-fi ( or hi-end, as they say) - and it was exactly the same: a lot of talk about gear, acoustics, frequency curves, vibrations, second reflections, materials and circuits, and very rarely the music was being mentioned. Hi-fi buffs usually know music better that an average guy, but a relatively small percent of them really understand it, very few attend classical concerts and a lot buy a system that costs you an arm and a leg and and acoustically treat their rooms turning it into some sort of a warehouse, only to listen to some compressed, overprocessed pop c**p. They are proud that their system allows them to count a number of fiddles in the orchestra and they can hear every cough and rustling in the audience. This is the exact equivalent of pixel peeping, "super sharpness", "creamy bokeh", and other stuff that is being talked about most of the time.
So it is exactly the same here, people buy "hi-end" cameras and shoot their cats and cars. But both hi-fi and photo gearheads get a great kick out of it because they love the gadgets and the technical side of their hobby. And it is easy - there are instructions and manuals, and you know exactly what happens if you press the button. And it is easy to give an advice, because all the answers are there on the net. When it comes to creative side of things, all of a sudden it all gets complicated, vague, personal and ambivalent. No buttons, no manuals.. sharpness as a creative tool becomes a bit more complex compared to sharpness as such.. So C&C, even if you get one, is also mostly about the technical stuff rather than a creative idea. I guess this is becase creative ideas are very difficult, first to grasp, then to analyse, and finally to put into words. Especially for a guy like me when words are foreign

Even if you read books on photography, most authors, established photographers, struggle with their "creative analysis" and succumb to cliches, artificial clumsy concepts or sheer banalities.
