Well, didn't want to go too far, in the first place. I am fond of photography since I was 14, I know a lot, but I am far, far, far from being a photographer, in the best case You could name me a "Sunday photographer artist" - sometimes my wife tells me how good my pictures are, but I suspect her of politeness !

.
I used "focus" more in the metaphorical way, with a hint of allusion to the photographic meaning. (plus, me, writing in English ... )
This reminds me a discussion with one of the Europe's finest English interpreters-translators: I asked him, as everybody speaks (some sort of) English, if the generalized daily massacre the of English language is not hurting him.
And he answered me that it is frustrating almost all the time, sometimes physically painful. As it's quit easy to make some basic English skills, nobody goes deeper, into the extreme richness of the English language. As he put it, it's a bit like seeing a Sunday driver going every week-end to the mall driving a Lotus. A guy fiddling the only 2 chords tune he know on a Stradivari.
Just like photography: it's so easy to take a shot, that almost no one realizes how much more is in it beside pushing a button.
