The Social Metaphor
(For Network Protocols)

People act differently according to situation, who’s around,
content, and context.
Think about the different social interaction protocols we
engage in:

One-on-one talk




Several people





With a friend
With boss
In a noisy environment


Should I go last?
How aggressive?
Whisper?
Moderator?
Group meeting
Business meeting
Get Emotional?
Family dinner
Remote interaction (teleconference)
Many people

Open discussion?
Raise my voice?
Can I interrupt?
State my mind?
Do I have to answer?
Lecture
Should I go first?
