LinkedIn began in 2003 and has since grown to over 50 million members worldwide, establishing itself as the leading professional social networking platform. While maintaining a focus on business relationships and opportunities, LinkedIn faces strategic dilemmas around whether to remain a closed platform or open up, how much to incorporate social features while keeping a professional focus, and how to best expand globally while addressing regional differences. Overall, LinkedIn is positioned for continued growth by balancing these considerations and responding flexibly to changes in the competitive landscape and economy.
