Written Language Mistakes Unique to America

Despite what you've heard, people who speak British English and those who speak American English can usually understand each other, once you get away from the most extreme accents. However, once social media became a thing, suddenly millions of people who previously communicated only in speech were suddenly typing out their thoughts for the world to see. That's when Laurence Brown, who makes a living comparing Britain and the United States, noticed some writing quirks that appear in American English, but wouldn't happen in Britain. 

He's not really picking on Americans, but pointing out that some of these mistakes arise only because of the differences in how Americans use the language, which he explains along the way. There are also writing mistakes common in British English that would never, or rarely, happen in America, and he promises to make a video about those in the future.
