Well all 'this' stuff, just again proves to me that french is not a language for the peuple, but for the intellos. That all french kids have to try and understand all this and if they haven't and have got much of it wrong, will penalise them for the whole of their lives and interfere with careers. Because the truth is that some of us are better at say sums and other things, than 'this'.
And as has been pointed out, french journalists who should know better, still make mistakes. And I am, as I have been for many years, singularly unimpressed with all 'this'. There is little egalité if part of the population are unable to get to grips with the complex grammaire of their own language.
Brings to mind a very good friend of mine (not french), internationally renowned in their field, and their written english is often iffy, because in spite of a brilliant brain, are probably a little dyslexic. The good thing is that these days, their english mistakes are picked up on spell check. I often wonder how they would have faired in french education. I do know that their moyenne would have been low.
