Acronyms and initialisms. From an informative Wikipedia entry: "...The New York Times guide recommends following each segment with a period when the letters are pronounced individually, as in K.G.B., but not when pronounced as a word, as in NATO. The logic of this style is that the pronunciation is reflected graphically by the punctuation scheme."

On the misuse of apostrophe's (did your eye just twitch?) and our increasingly rhetorical language. "Graphic designers, who favor an uncluttered aesthetic, dislike hyphens. They are also partly responsible for the disappearance of the apostrophe....Defenders of the apostrophe insist that it minimizes ambiguity, but there are few situations in which its omission can lead to real misunderstanding. The apostrophe is mainly a device for the eye, not the ear. And while I plan to keep handling apostrophes in accordance with the principles I was shown as a child, I am confident that they will either disappear or be reduced to little baubles of orthographic bling."
