Netiquette is a collection of social conventions which dictate the way in which people interact with each other on the Internet. The term is a portmanteau of “net,” short for “Internet,” and “etiquette.” Like social etiquette in real life, the rules of netiquette are commonly in flux, and they may vary significantly between different groups of Internet users and across different cultures. Some websites even post their own netiquette guidelines under headings such as “rules” or “comment policies” to provide directions to their users.
