I have seen more than a few questions pop up regarding the meanings, grammar, etc. of clearly non-grammatical prose (as @Matt put it here) used by authors to imply the dialect, accent, lack of education, etc. of a speaker or character in a story.
The most recent example is the question on which @Matt commented, Why is this possessive, not objective case?
It seems to me that these types of questions aren't really about English as a language so much as about the author's stylistic preference, and to me that seems entirely off topic. Do others agree, or is it just me?
The linked question does have two close votes under "too localized" (one mine), but to me it seems less localized, as these types of stylistic choices are fairly common in certain genres of literature, and rather entirely off topic for a site based on learning the English language.
If the community tends to agree, it might be useful to make a note if it somewhere official.
If this has been discussed elsewhere, please let me know, but I couldn't find it.
