LinkedIn has over 313 million users globally and is available in over 200 countries and 20 languages. 40% of its users check LinkedIn daily and it had over 1 billion total endorsements as of March 2013. However, users on average only spend 17 minutes per week engaged on LinkedIn and interactions are largely limited to professional purposes rather than general social engagement. LinkedIn provides opportunities to connect with others in similar fields, find clients and career opportunities, and tools like Q&A and targeted ads can help build professional networks and engagement, but it faces the threat of low participation from younger demographics and reputational risk from negative actions.
