One of the strengths of Linkedln is the powerful link building and traffic driving ability. Just as other social networks do, Linkedln has a social sharing button that enables you to share content in your status updates.
This works especially well for business-related content and can lead to viral effects. Business content often gets shared more often via Linkedln than via Facebook.
