New words are regularly added to the English language. Few new words are as annoying, both in their overuse and the sound that they make, as "app" and "tweet." Yes, I know "tweet" isn't really a new word, but until recently no one ever used it with any regularity. I know "app" is short for "application," and I appreciate that many people find a four-syllable word like "application" cumbersome, but the person who decided that it would be catchy and acceptable to refer to anything as an "app" deserves to be whacked in the face with the branch of an apple tree.
Too bad there isn't an app for that.
