Well said .. there is some utter nonsense talked about sharpness in many places. ;-)
My general feeling is that (for some) it's much easier to explore sharpness and other technical craft issues relating to image 'quality' than address the fact that their photos just aren't that great, and that concentrating on technical issues is just a way of avoiding concentrating more on the image content, or other less quantifiable/tangible aspects.
Of course this isn't new - photography has a long history of people spending a lot of effort on technical differences very few would ever notice. I'd just note that this behaviour becomes much easier with digital ;-)
The technical aspects (refining my 'craft') are important to me, but only as part of the whole image creation process. The technical has a vital part in my commercial work, but I know that very few clients are ever going to ask for it by name - to them it's primarily about the content of the image and representation of ideas.
Colour management is another area I see a lot of this, with a spurious desire for 'perfection' and 'correct' colours for applications where no-one could ever know (there are times for great precision, but not for photographic work I do)
Curiously enough, I only ever find such behaviour (in colour management and photography) in men ;-)
It's astounding how many guys at my local camera club pay thousands and thousands of pounds on the latest and greatest gear, agonising if this particualr lens has a slightly better cache (notice I didn't say Bokeh)...and yet they neglect the certain and clear need to attend workshops or training courses from the very experianced to hone their craft further. I guess it's why they are called camera clubs and not photography clubs.
My landscape and wildlife skills came from attending a lof of Guy Edwardes workshops and even now I still learn new things. When I went on my first workshop with him, I took my existing skill set and added it to what he was showing me. I learnt a lot, and it refeined me as a more general photographer. Within my wedding context, my panning skills are vastly improved. My compositional pallet and exposure control were exapnded. What i brought into the workshops were my gear, existing camera craft, workflow and photographic eye.
