Digital etiquette helps people avoid awkwardness in communication and offers ready-made instructions on how to behave in different situations online. It increases work efficiency, improves business reputation, and also helps with relationships with clients, colleagues, and partners; it protects your boundaries and, simply, helps you be a decent person. In her book, Olga Lukanova compiled all the rules together and explained them from the standpoint of convenience, safety, saving users’ resources, and respecting personal boundaries. All the rules were tested in the Telegram channel “Digital Etiquette” with the help of polls and feedback from subscribers.
