LinkedIn is a social networking site designed specifically for the business community. The goal of the site is to allow registered members to establish and document networks of people they know and trust professionally.
A LinkedIn member’s profile page, which emphasizes employment history and education, has professional network news feeds and a limited number of customizable modules. Basic membership for LinkedIn is free. Network members are called “connections.” Unlike other free social networking sites like Facebook or Twitter, LinkedIn requires connections to have a pre-existing relationship.
