Since the world wide web became public, the internet has been changing the
way that companies communicate and conduct business. Social networking
sites, online communities that enable people to communicate and build
networks based on similar interests, activities, values, and ideas, have
significantly contributed to that change. These sites can provide a number
of advantages to employers, such as publicity and marketing, recruitment,
and employment screening. Improper or careless use of such sites, however,
may result in tort liability, can compromise confidential information and
business reputation, and may lead to discrimination, privacy, and freedom
of speech suits.
