Forrester Senior Analyst TJ Keitt does not think small. "The free exchange of ideas changes the world," he starts when asked to define social business. He adds, "It can also change companies." Social business is about tightly woven networks of employees interacting with loosely woven networks of partners, suppliers, and, of course, customers. The goal is for firms to become more nimble, acquire more knowledge, and share it faster. This is not about Facebook. Social business platforms such as Jive, Salesforce Chatter, TIBCO Tibbr, Microsoft SharePoint, and others are designed specifically for the social business.
