You speak of elitism as though it's a bad thing. I think it has its place.
When people are studying to do something well (like, say, heart surgery, or writing), it seems to me sensible to ask those who do it best for advice, and then learn from the advice. But that's inherently elitist. See Jimbo Wales vs. Larry Sanger on Wikipedia for elitism and anti-elitism.
If you dislike elitism, then you choose not to ask those who are best at it. You take your wisdom, like Wikipedia, from the masses. Writing is a matter of personal taste, so nobody's going to stop you from punctuating randomly, or single-handedly evolving the language.
But if you ever take up an interest in heart surgery, please tell me where you live so I can avoid that place.
