There is growing concern over how we behave and interact online, from fighting, incivility, rudeness, and even criminal behaviors like cyberbullying, to simply adapting old forms of etiquette to a new landscape. This book, updated from an earlier resource, provides younger readers an introduction to this timely topic, a subject that they are both engaged in forming themselves as "digital natives," and one they also often require guidance in. It informs readers about the polite and productive use of social media networks and mobile platforms and discusses pressing issues of etiquette within families, among friends, and in educational settings.
