To add to the opportunities:

1) The internet is a rich source of 'patient narrative data' that can be mined effectively to create conceptual modeling of patient experiences of ill health and physician’s handling of their illnesses.

2)  Improve health-care through clinical problem solving utilizing concerted experiential learning in conversations.

3) Promote transparency in health care and qualitatively study its processes to assess the role of experiential vs. experimental evidence in influencing healthcare outcomes.


Threats:

1) Mushrooming of destructive feedback platforms based on servers in unscrupulous jurisdictions that are driven by advertising from vested interests and purveyors of therapeutic snake oil.

2) Overly concerning the patient and caregiver about the health-care process.

3) Breaches of privacy and confidentiality
