My first writing instrument was a Smith Corona manual typewriter that, like all the typewriters of its day, did not have a separate key for the exclamation point. Creating an exclamation point involved three steps: you had to type a period, then hit backspace, then type an apostrophe. This process took just enough effort to make you reconsider whether you really wanted to use an exclamation point at all.
Today it takes a mere keystroke to produce an exclamation point, and as a result you see them everywhere. Everywhere! Perhaps the inventors of the typewriter knew what they were doing. Perhaps the unwieldy design of those early machines was a futile attempt to regulate a form of punctuation that had so much potential for abuse.
