I sort of agree with some of what you're saying janebb, like I have mentioned before on here, I have a fair understanding of our language but when it comes to grammar, I am certainly not top of the class by a long chalk.
However, I must say that I can show fierce pedantry when I receive text messages from people with (what seems to be becoming the norm) text-chat or text-talk. What a load of shite it is, it's a different language and I can only see it being a disadvantage to childrens education in the future.
I myself sometimes use words like 'gonna' for 'going to' for ease and swift replies, but I'm afraid "C U ltr m8" just doesn't quite cut the mustard.
One point is though. We would (as crossword enthusiasts) be ignorant to not keep our eye on it because we will see a day in our lifetimes that will have some form of 'text-talk' written into a cryptic clue I'm sad to say. And that's the day the ballonn will have gone up for all of us.
