A witty, informative guide to writing from Random House's longtime copy chief and one of Twitter's leading language gurus--a twenty-first-century Elements of Style. We're all of us writers: We write term papers and office memos, letters to teachers and product reviews, appeals to politicians, journals, and blog entries. Some of us write books. All of us write emails. And we all want to write them better: We want to make our points more clearly, more elegantly; we want our writing to be appreciated, to be more effective; we want--to be quite honest--to make fewer mistakes.
