Here's just a taste:
What I bemoan is the cheapening of the exclamation mark in all forms of written communication. For the past half century, Strunk and White's classic little primer, "The Elements of Style," has provided students with a north star to clear writing. In its simple, straightforward, scolding tone, it admonishes writers to reserve exclamation marks for use after "true exclamations or commands." Or, as many an editor has reminded me over the years in calling for restraint in punctuation or typography: "We have to save something for the Second Coming."
Today, the exclamation mark has become so common that its power has been lost. In fact, it has become so expected in e-mail, texts, Facebook and 140-character Twitter communications that its absence is considered a statement in itself.
