The idea of stakeholder circles is spreading! Google has begun beta testing a new social networking system that uses the concept of circles to manage friends.
Not in same way as our Stakeholder Circle®, but the Google + Project now lets you put your social contacts into different circles. The Google circles makes it easy to put your friends in one circle, your family in another, and your work colleagues in another; then manage what you share with each group.
Just for the record, we invented the Stakeholder Circle® in 2003, and the name is a Registered Trademark. Neither of the two developments above conflict with our mark, and naturally, we thoroughly support the idea of using circles to manage your communication with groups of significant people, friends or stakeholders.
