Depends what you want.
The majority of BST buyers just want food for teh Googlez. Mangled English and mistakes aren't a big deal when what you really want is the user to click on the ads next to the text. So as far as they're concerned, it's a sweet deal.
You want a well researched, well written and copyedited article? You're looking at a $1 per word. Sales copy 2-3x that.
And on that note, if it's sales copy you're looking for, English majors are the worst people in the world to write it. Although the stuff they produce is highly literate, it's usually too fancy to sell well. Good copy is conversational, and that often means doing things that piss grammar freaks off.
Like starting sentences with a preposition.
And using very short paragraphs.
Or sentence fragments.
I have a standard answer to English grads who pick at copywriting for being too casual. It's "so what percentage does your writing convert at then?"
That said, you have to know the rules to break the rules, and having re-read OP, I do agree that the quoted post screams "non-native English speaker".
