Use Case Scenario
Alice takes her child to the doctor for a cold. The doctor recommends a routine test. Later, Alice discovers the routine test was not so routine after all, as it was to rule out the possibility swine flu, a recent epidemic. Alice feels that the doctor misrepresented the test, and wants to share this with her friends, but is reluctant to do so, since casting the doctor in a negative light can have repercussions in her care at a later time. The information is made available to a network of people (Alice's friends) without the exact source of that information being made apparent.
