Given how messed up the English language is, I do not worry about it. After all, English in the US is a mish mash anyways of various languages and as such is usually allowed to be more flexible to an extent. Also, if you think this is beholden only to English, you would be mistaken. Also, as times change, speech changes, It would be impossible to dispute this. You can look at the number of languages out there that are very similar and derived from a common base.
Another point on the this is that IF there were only one way to write something, every school would teach it that way, grade school up to graduate schools. As there is a vast range of levels, it would indicate that there is almost always more than 1 method. now here I am talking structure.
I see no excuse for misspelled words. Seeing a word like Xtrem or Xtreme annoys me, especially if it is a business.
I remember then that I used to frequent a bar called dickheads. yes it was called dickheads. Not very PC is it. Well the city didn't think so either and so the owners cleverly changed the name to Richard Cranium's. Means exactly the same thing, just said differently.
I decided that if it is understandable, I do not much care, unless it is something VERY important. I could care less about a newspaper not using one person's standard as long as the reporting itself it solid. Now an instruction manual for a space shuttle, THAT is important.
I figure we have enough things to worry about in this life that being a grammar nazi is pointless.
