Patterns — update

• Active broadcast of presence

  Users may actively choose to automatically provide updates when they want to share presence information, to increase both the relevance of, and control over, their sharing.

• Enable/Disable Functions

  Allow users to decide granularly what functions they consent to before the function is used.

• Reasonable Level of Control

  Let users share selectively (push) and make available (pull) specific information to predefined groups or individuals.

• Reciprocity

  Let users benefit according to the contributions they make.
