Are exclamation marks outdated? CAPS LOCK IS QUITE GOOD AT GIVING THE IMPRESSION OF SHOUTING. In fact, from the first word of the 'capped' sentence that you read, you would already know that there is some shouting going in, whereas if you were reading a sentence that ends with an exclamation mark, you would have no idea that the sentence was meant to be emphasized, leading to only the last couple of marks "sounding louder" in your inner voice!
