I think spelling and grammar is getting worse everywhere these days. The number of times I've seen mistakes in newspaper articles, online news (including for major providers like the BBC), official documents etc. I think a lot is an over reliance on spell checkers which can't pick up a lot of mistakes. It's where words are substituted for the wrong ones, or where a sentance reads correctly, but not in the context given (the "Eats Shoots and Leaves" problem). It's the sort of things where a proof reader would (or should) pick it up, even just the person writing going back over it, but a spell checker wouldn't. I think computers don't help either, as they allow people to type faster than their brains work, so luiness toy are paying attention and chekc rtha you havee types it's heay to make mistakes (that latter part was me typing without correction). I don't mind the odd spelling mistake though. We all do it and usually it's clear what it meant, unless it's something official where it's expected to be right. The only problem is when mispellings can cause confusion between different words. Technical words are bad for that, I can think of quite a few where one simple mistake can either make it mean the total opposite, or can make it impossible to tell which of two different words has been spelled wrong.
