== Errors attributable to American punctuation—have you seen any? == 

  
 Lguipontes, on WT: MoS, you say alluded to American quotes leading to errors, and I am guessing that you refer to the U.S. practice of putting periods and commas inside the quotation marks, "like this." 

 Have you ever seen American-style punctuation cause errors?  What were they?  I've heard a lot of people say "U.S. punctuation causes confusion and mistakes!" but no one has ever given a real-world example or even a convincing hypothetical example.  Have you seen one? 

 A lot of people who don't like American punctuation argue that it causes errors, but none of them have ever given a real-world example. In all my years of writing and editing in U.S. English, I've never once seen someone make a mistake or misunderstand text because the period or comma was inside the quotation marks. I want to know if errors attributable to U.S. punctuation are Bigfoot (mythical) or the platypus (thought to be mythical but eventually proven to exist).
