I think the degree of fault tolerance depends on the age of the reader. My first computers used discrete transistors. My high school English teacher was a strict grammarian. I paid close attention because I was dating her daughter, also a strict grammarian. To this day the misuse of "to" for "too" will bring my brain to a full stop. I am moderately adapted to the confusion of "fewer" vs "less". (It's countable vs uncountable.) And I even use "they" as a gender neutral third person singular, but you should never do it in formal writing.

I read an article sometime in the past year that maintained that all the prissy rules were imposed on a perfectly good language by self-imposed arbiters of the language. Sorry, I cant locate it at the moment.
