LinkedIn, though it’s still a relatively small company (with roughly seven thousand employees), has more than a hundred data scientists. Google has more than six hundred. These numbers bespeak a major commitment to big data.

It’s your contact manager. It allows you to organize and manage all the people in your professional life. You can add your email and phone contacts to your LinkedIn connections—making it the only tool you need to find the key players in your community, even when they switch jobs and their email address changes.

LinkedIn recently developed a new set of unified search capabilities, for example, which use big data to predict the types of content a user is most likely to be interested in, and optimizing the presentation of results.

Although LinkedIn is still used as a job search and recruiting tool, its greatest value comes from the features that allow you to learn and grow, and to become a part of communities.
