All of the mistakes outlined in this thread bother me, too. I'm not a linguist by any stretch, but I learned to read, write and spell properly nearly half a century ago. I don't understand what's so hard about it, or why so many people don't get it, and don't care. I also don't understand why so many of them are in charge of making signs and writing stuff that literate people have to read!
So often, I have seen sentences with "ect" at the end. Who told people that the abbreviation for et cetera is "ect"? Why is it so difficult to understand the difference between "to" and "too"?
If this kind of thing bothers you, don't go to eBay. You'll find that there is often an apostrophe in "shoes," and that they have heals and souls and a tounge. Very few people can spell Reebok, even while looking at the box, and I keep seeing new variations on Skechers that I didn't know were possible to make.
It must be even harder for children to learn the language now, with brand names being intentionally misspelled, and with URLs containing words all run together without spaces or capitals. It seems no one teaches them to be able to tell the difference.
Whoever decided that the "whole language" method was a good thing, where you get marks for trying, even if the words you spelled are not even close, should have been fired. Somebody had to come up with that insane concept, and other people had to agree with it, and still more of them had to implement it in schools. Now there have been several generations of children who have no idea how to use the only language they may ever speak.
kthxbye lol.
Ugh.
