LinkedIn is a social network for job-stuff. People put their resumes on there and then add friends and people they work with or meet as "contacts." You're supposed to have one, though somebody being offered a job out of the blue on the merits of their LinkedIn page is both absurd and unheard of. Nevertheless, maintaining an updated LinkedIn profile is one way to maintain good internet hygiene and control what interviewers/HR finds when Googling you.
