For years now, studies and news articles have talked about the value of using social networks to make potential employment contacts. Today it turns out social networking is the job—or at least part of it. The proliferation of sites like Twitter and Facebook as marketing tools has led to a boom in social-media positions at just about any company with a Web presence. In response, colleges are adding related courses and even entire M.B.A. programs to prepare students who are interested in turning an otherwise amusing hobby into their profession.
Sigh.
