And up there, you see what looks like another rule violation – the end quote mark outside the period. I remember the rule from my grade-school grammar about the position of the end punctuation inside or outside quotes. If the entire sentence was a quote, then the period goes inside the quote mark; if it is a quoted section at the end of a sentence, the period would go outside. Not so much anymore in modern typography. The style now is leaving the quote mark outside in either case as it just plain looks better that way. The English language, both spoken and written, is dynamic. Even if "properly" expressed in print, some readers may be confused. It's always best to be clear and simple. You don't get much on style points, but fewer readers will be confused.
Gaaa, listen to this old man prattle!
