Gautam Ghosh is a social business consultant who has been engaging with virtual communities since 2000 through blogging, tweeting, and maintaining a website. Social technologies are bringing fundamental shifts by moving authority to users, focusing on niche relevance over broad topics, and allowing people to earn visibility through social trends rather than buying visibility. These changes impact how companies approach content, talent management, and the nature of work. Companies are using social tools internally for collaboration, learning, and crowdsourcing innovation from employees. HR can facilitate internal communities by connecting employees and acting as change agents.
