Aren't there more reasonable ways to get attention than dumbing down conversation?
It seems like more and more it's becoming more difficult to understand what anyone is really saying. It only takes one word to change the whole meaning of a sentence.

That's all true. But I would make the argument that WE typically don't have conversations with people for which basic sentence structure is beyond grasp. No?

THOSE people tend to hang out in the dark recesses of the Internet, or spare us the confusion by text messaging other teenagers people.

Me no Grok.

I'm referring to Daves statement that he intentionally uses incorrect grammar to get attention.

I very much appreciate anybody, anytime pointing out my grammatical errors. How else will I learn?

The "smarter than you attitude", imho, is usually self-inflicted because we feel silly knowing we should know better.

I used to do joking kinds of corrections, but have stopped doing even that for exactly the reason Giz states. I do, on the other hand, say a couple of Our Fathers and a Hail Mary or two on behalf of the writer.

I try to ignore it except when it begins to impede a discussion/debate/argument. Then clarification is needed.

Feel free to "our fathers" and "hail mary" me verbally.

Youse guys or Youse, even Y'all I understand...the one that I don't get is youens...is youens going to the store....only hear it in southern MO and southern IL.

or Ill...not a medical condition but a state of manors...as in
my child is ill today, something to do with how the child is
behaving in public

I suspect it comes from the Irish versions, "yins." Wikipedia has an article on it, if you're curious. It's pretty common in parts of PA, so it doesn't sound so weird to me.

You know, ever since English got rid of "thou," which was singular 2nd person (like "tu" in Spanish and French, or "du" in German), we've tried to reinvent a distinct form of the plural, making "you," which originally was the plural (or formal singular, as is the case with German, Spanish, and French, where the plural second person is also the formal first person).

So I vote for going back to "thou/you."

As if!

I was going to mention the "who" part being used in reference to people. Since you stated that your statement was referring to The Wire and Treme, the first and third "that" are really superfluous in the meaning being conveyed. Capiche?
