I think one of the main points that needs reiterating is that to "get their message across" does indeed require the correct use of grammar and use of the correct words. Miss spelling thier will not harm the meaning or context of a sentence as much as using there instead.
How many of you get part way through a question posted here or elsewhere and loose interest in trying to decipher the meaning because of poor grammar!
What is going to happen when our arithmetic rules get as mangled as our language, someone will get under or over paid, then the new bridge will fall down!
Incidentally where exactly did we get learning "The three R's" for Reading Writing and Arithmetic.
By the way, love this thread. I thought it was serious for a moment until I realised that most of the people professing their knowledge of English were clearly wrong. Not sure what the subversive intention is by giving people incorrect grammatical information, but very entertaining anyway.
IMHO, outside of a formal environment, getting upset at someone's spelling is pointless. Firstly, as long as they get their message across, who cares how they do it. Secondly, poor spelling and grammar is more likely a language, cultural or educational matter. Telling someone to get the spelling in order isn't going to automatically make them better at it. Instead, its just going to discourage them from being an active participant here. And I know that is nobody's intention or desire. Maybe there are better ways to help people? Perhaps find a polite way to point it out in a thread where you see a problem? At work I often come across people who aren't as good at communicating as they want to be. FWIW, my current favourite solution is Toastmasters.
