Should you do your “due diligence” or your “do diligence” when you set out to buy something more expensive than a box of Oreo cookies?

Christina Desmarais has the answer to that question and 19 others in an instructive article every business writer should scan. She cites errors found on websites belonging to Oxford University, the BBC, the White House, the New York Times and other high-profile organizations. Her examples may peak — I mean pique — your interest and save you from a minor embarrassment.

She notes that many of the errors won’t be caught by a spell checker. To test that comment, I used her examples in a Word 2013 document. The grammar checker identified only seven errors; it missed “shoe-in” and  “sneak peak.” It’s enough to disrupt anyone’s piece peace of mind.
