[edit] Company info

LinkedIn's CEO is Dan Nye. As of February 2008, founder and former CEO Reid Hoffman, previously an executive vice president of PayPal, remains President of Product and Chairman of the Board.^{[citation needed]} LinkedIn is located in Mountain View, California, and funded^[4]by Greylock, Sequoia Capital,^[5] Bessemer Venture Partners, and the European Founders Fund. LinkedIn reached profitability in March 2006.^[6]

[edit] Features

The purpose of the site is to allow registered users to maintain a list of contact details of people they know and trust in business. The people in the list are called Connections. Users can invite anyone (whether a site user or not) to become a connection.

This list of connections can then be used in a number of ways:

• A contact network is built up consisting of their direct connections, the connections of each of their connections (termed second degree connections) and also the connections of second degree connections (termed third degree connections). This can be used to gain an introduction to someone you wish to know through a mutual, trusted contact.
• It can then be used to find jobs, people and business opportunities recommended by someone in one's contact network.
• Employers can list jobs and search for potential candidates.
• Job seekers can review the profile of hiring managers and discover which of their existing contacts can introduce them.

The "gated-access approach" (where contact with any professional requires either a preexisting relationship, or the intervention of a contact of theirs) is intended to build trust among the service's users. LinkedIn participates in EU's International Safe Harbor Privacy Principles.^[7]

The feature LinkedIn Answers,^[8] similar to Google Answers or Yahoo! Answers, allows users to ask questions for the community to answer. This feature is free and the main differences from the two previously mentioned services are that questions are potentially more business-oriented, and the identity of the people asking and answering questions is known.

[edit] Privacy issues

• Non-members can check whether or not a person is a member. As of August 2007, this feature can be disabled.^[9]
  • There is no automated way to remove oneself from LinkedIn. The official method is to file a customer support ticket.^[10]
    • It is not clear that invitation messages are actually from the individual they claim to be from.

    [edit] Sites with comparable features

    Various websites such as CareerBuilder.com, Yahoo! HotJobs, and Monster.com specialize in job search. Reputation systems are increasingly common across the Web. Ryze was one of the earliest online social networking sites to offer online business networking, but more recently most social networks facilitate professional networking to one degree or another, either as native features or via third-party software application widgets. Many of the specific LinkedIn features (such as answers or testimonials) are common web features.

    [edit] Mobile version

    In February, 2008, Linkedin introduced a mobile version of its web service, available in six languages: Chinese, English, French, German, Japanese and Spanish. ^[11]
