Social Normalcy

Social Normalcy is defined as "The direct correlation of on-line communication attitudes and actions with those characteristic of real-world communications between originating and destination parties, with real-world communications being the model."
Respect Traditional Messenger Role
It has long been tradition that while "nobody shoot the messenger," the messenger also "never reads (or scans) the message."
Participant Data Access
Carried messages available to third party only in response to a legal court order of the government in which the service is hosted.
Realistic Expectation of Privacy
False conclusions born of black and white evaluations that, if every communication cannot be kept 100% secure from the possibility that another party will learn of the information infers no effort should be made to protect the information at all, are strictly forbidden. Throughout history all communications have involved some level of trust in the messenger, the medium and the recipient.
Distinction of Public and Private Conversation
Legitimate public conversations have an unknown audience breadth with unknown recipients. A private conversation has recipients of a known identity and number. Social media, by nature of the word "media" is never private. Communicators need a distinct choice of opportunity between private and public communications.
Definition of "private data"
The definition for what data is private, and to what degree it is private, is entirely at the discretion of the originator or the recipient, with the originator being the ultimate authority.
Control
Otherwise known as "blacklist vs whitelist." Normal communications outside the electronic realm are whitelist communications. We select whom we wish to communicate with and when. This would be supported by a good social network. In social media we are under a continuous barrage of interlopian communications we must blacklist with filters that is both frustrating and about as effective as holding back an ocean wave with your hands. Communication source and content control must lay with the recipient.

Note
"Respect Traditional Messenger Role" and "Participant Data Access" are not in conflict. It is possible for a messenger to turn over messages to appropriate authorities upon legal court order without ever having read the message themselves.
