Social Networking v Interpersonal Networking

Finding a job in today's world is both more complex and simple than it was a decade or two ago. In the past we would look for jobs in the newspaper or go around passing out our resumes in hopes that we'll get called back for an interview. A critical part of finding a job has always been networking. In the past we would usually meet face to face with people and exchange information however, now we can communicate and network with people over social media. Which of these two do you think is superior? Does it depend on the job or is one ahead of the other? That important question can be the difference in getting an interview or getting tired of waiting for a call.
