Social computing can be used and viewed in many different ways in an enterprise: social networking, expertise discovery, social information identification or discovery, knowledge distribution, social brainstorming, project workgroups, communities of practice, and many more. Each of these tasks embody some action on information, people or the software environment and can exist in a choice of different social contexts or perspectives: individual networks, small ad-hoc meetups, defined workgroups, long-term communities, and mass collaborations. Finally, these can exist across a mix of boundaries: internal, through the firewall, and external.
