For business people, LinkedIn is fertile ground for establishing oneself as a so-called thought leader. Last month, the professional social network got into the business of naming thought-leaders and enabling members to follow them.

In an Oct. 2 blog post, LinkedIn unveiled the new feature, in which its users can follow other members—at the time it was 150 pre-ordained thought leaders—in much the same way one might follow a person’s tweets. Since the initial launch, LinkedIn has set about expanding its network of thought leaders.
