that thinks putting one word in a sentence in all caps is yelling...not merely emphasizing a word.

Using capital letters to indicate strong feeling may be the most famous example of typographical tone of voice. But there are different kinds of strong feelings. Linguist Maria Heath asked a cross section of internet users to rate the difference in emotion between a message in all caps and the same message in standard capitalization. She found that all-cap styling made people judge happy messages as even happier: “IT’S MY BIRTHDAY!!!” feels happier than “It’s my birthday!!!” But it didn’t make sad messages any sadder: “i miss u” is just as pathetic as “I MISS U.” When it came to anger, the results were mixed: Sometimes caps increased the anger rating and sometimes they didn’t, a result which Heath attributed to the difference between “hot” anger (FIGHT ME) and “cold” anger (“fight me”).
A single capped word, on the other hand, is simply EMPHATIC. Looking at examples of all-capped words on Twitter, Heath found that the most common single ones included NOT, ALL, YOU, and SO, as well as advertising words like WIN and FREE: the same kinds of words that are often emphasized in spoken conversations (or commercials). When we want to emphasize something in speech, we often pronounce it louder, faster, or higher in pitch—or all three at once. All caps is a typographic way of conveying the same set of cues.
