LinkedIn is a free business social networking site that allows users who register to create a professional profile visible to others. Through the site, individuals can then maintain a list of known business contacts, known as Connections. LinkedIn users can also invite anyone to join their list of connections. LinkedIn offers an effective way by which people can develop an extensive list of contacts, as your network consists of your own connections, your connections’ connections (2nd degree connections), as well as your 2nd degree’s connections (called your 3rd degree connections). From this network, individuals can learn of and search for jobs, business opportunities, and people. LinkedIn also serves as an effective medium by which both employers and job seekers can review listed professional information about one another. LinkedIn follows strict privacy guidelines wherein all connections made are mutually confirmed and individuals only appear in the LinkedIn network with their explicit consent. Other LinkedIn features include paid accounts that offer more tools to find people, and “LinkedIn Answers” developed in January 2007. A free feature, “LinkedIn Answers” allows registered users to post business-related questions that anyone else can answer.
