past it's best-before date; How about Orwell "exhibiting postmortem turbine energy?"

An article published on the first day of 2010 - "'Buzzwords' deserve cultural banishment" in The Vancouver Courier on January 1, 2010 - contains two errors. All was good until the final paragraph. It's best-before date should be its best-before date (no apostrophe in its), and how about putting that question mark after the closing quotation mark?
