Depends where you live. I can give you the San Francisco Bay Area use of linkedin 1. sharing linkedin accounts is more natural than sharing FB accounts here. And I'm talking about social events, friends, meeting someone new. Not about formal stuff... It's really your social profile here. The rest people don't really care anymore since it's all about networking 2. Looking for jobs. If you're looking for jobs and you're not on linkedin then you're invisible in the Bay Area. Plus, all companies career websites ask for your linkedin profile 3. You can lie to a lot of people about your career. Linkedin acts as your professional ID too.
