LinkedIn's Reid Hoffman: Careers in the Networked Economy Reid Hoffman knows a thing or two about networking. Not only did he launch one of the most successful Internet companies of the past decade, LinkedIn, the social network for professionals, but he's developed a formidable network of his own, one that's given him the opportunity to invest such high-flying Internet start-ups as Facebook and Zynga. Hoffman stopped by TIME's office in New York City to discuss his new book, The Start-Up of You, which offers insight into how to further your career in the digital, networked economy.
