Well this thread was an interesting read!!
I am a good speller in general and like you, Terry, if I spot a mistake after posting, try to edit it. My biggest problem is the one a few posters such as Fe2O3girl have mentioned - I'm mildly dyslexic. It's not that I spell words wrong, I just type words in the wrong order and a spell checker won't pick that up for me. I can re-read a post three or four times and still not spot my mistake. It happens (usually on long posts!).
I can't really make much comment on our younger generation's spelling, except that I believe computer spellcheckers and cell phone predictive texting have a lot to answer for! Children don't seem to have to actually write much any more - with the possible knock-on effect that reading skills may be reduced also.
I do agree with you that there are some 'lazy' spellers out there - that's their loss and if they find themselves unemployable or in low-paid, 'unskilled' jobs, they only have themselves to blame. What do we do with a generation which seems to want everything handed to them on a plate?
I guess the mistake with your initial post which invited all the varied responses (and maybe what fifi is getting at too) was that you didn't appear to differentiate between the lazy spellers and those who do have genuine reasons for their errors - such as dyslexia, MS, English being their second language etc. They don't deserve the criticism if they're trying their best to get their point across.The problem is how do you differentiate on a discussion board? In that respect, it's better to criticise nobody for their spelling.
