LinkedIn is a business-oriented social networking site launched in 2003 with over 40 million registered users. It allows users to maintain a list of contacts called Connections and build up a contact network of their Connections and third-degree Connections. This network can be used to gain introductions to others, find jobs, people, and opportunities. Employers can post jobs and search for candidates, while job seekers can review interviewers' profiles.
