I don't really see any correct way of speaking, or how to say a particular word. All language currently spoken, is in flux. Dialects are a fact of life:http://en.wikipedia.org/wiki/List_of_dialects_of_the_English_language
Meanings of certain phrases reduced to strict rules of grammar, the improper use of double negatives, may have it's place in legal documents, and translations of the Bible and other areas where wording is crucial.

But in a forum where people speak english, and come from all walks of life, and locations that speak different dialects,, than the standardize English, it would hardly seem likely that they would need to be scrupulously correct or overly concerned with what they write measures up to the standardized model. Maybe broadening out in your understanding of how and why we have a standardize language may make it a little more easy to take,, for the correct spellers and grammar perfectionest when they see errors of this nature? Even with the nonstandardized use of english the meaning is often clear and easy to understand from the context and subject under discussion.
Not to mention some have a hearing problem, and the correct spelling of words they are not familiar with may not be that easy.One women I met spoke english with a french acsent so I asked her if she was from France, she said no and that her acsent that sounded French in origin was from a hearing impearment,, the way she heard the words is the way she spoke them, which sounded like a French acsent.
