PositiveScienceAlthough the title suggests that this book takes a prescriptive approach to language, discussing the \'rules\' for online communication, the content shows quite the opposite. McCulloch describes a variety of uses of the internet such as ListServs, texting, social media, and memes and explains how language—primarily English, with some examples from other languages—has adapted to each function without judgment ... McCulloch resists exploring internet language as a new phenomenon. Instead, she builds her investigations on older research into sociolinguistic features ... studies are woven into a compelling narrative rich with examples from her own online activities, a healthy dose of humor, and plenty of cat memes. Although it probably will not provide any novel insights for new media linguists, the breadth of topics covered—from conversation analysis to meme culture to the development of texting as we now know it—makes this book useful, engaging, and enjoyable.
