Are head hunters going the way of the dodo?

Ever since I was encouraged to join LinkedIn I have seen it grow in popularity. I have watched my network grow and even gotten recommendations from others. Many of my colleagues share the same story. With the size of our networks and the people we know, there are fewer reasons to go to a recruitment firm for a job placement. 

Indeed recruitment firms are only useful for specific and perhaps niche roles that cannot easily be filled by searching through LinkedIn. So while head hunters are not extinct, it should be noted that today social media is not just for sharing photos, raising money, or broadcasting an idea. Now you can get a job and perhaps launch a career as well.
