Personally, I get confused why the spell-checker for Chrome is so bad. I so often type words that it recognizes are wrong, but has no suggestions at all for, when the correct word is just a single character off. elipsis (ellipsis), elipses (ellipses), independant (independent), disserning (discerning)... How can it not find the correct word?
