I’m feeling sorry for this writer. I imagine this poor guy being told to write a blog post for Yahoo! Answers, and he’s unsure of his writing ability, but he gives it his best effort. So, I feel kinda like a bully pointing out something that could use “improvement.” Like this unnecessary description of a cliché as “common.” That’s the meaning of the word, isn’t it?
And the poor writer probably doesn’t have the benefit of a high school education. It’s almost understandable that he’d write their instead of they’re and your instead of you’re. And why should he know where to put a question mark?
So, the next time he’s asked to write something more complex than a grocery list, I’d advise him to say, “Thanks, but no.”
