In this day and age when knowledge workers are entering and exiting organizations practically on a daily basis, many organizations struggle with how best to arm their workforce with the knowledge they need to maximize their performance thereby increasing the organizations efficiency and effectiveness. Social media tools such as microblogs are emerging and can be used by organizations to foster informal learning, provide performance support and help create communities of practice that result in employees enhancing their learning and knowledge and improving their performance. It is worthwhile thinking of microblogs in the context of situated cognition to understand that learning and performance are intertwined in day-to-day work activities. While distributed cognition helps us understand and view microblog users in organizations as one system that drives the collective forward.

This research aims to uncover that microbloggers in organizations enjoy enhanced learning and performance improvement through the use of the tool and that this results in communities of practice.

Finally it is also important to note that because microblogs can uncover context, manage content and provide access to experts, they could be examined in the context of a knowledge management system and used not just to manage an organization’s knowledge but also to find an organization’s experts.
