Markets consist of human beings, not demographic sectors.
Conversations among human beings sound human.
They are conducted in a human voice. Whether delivering information,
opinions, perspectives, dissenting arguments or humorous asides,
the human voice is typically open, natural, uncontrived.
People recognize each other as such from the sound of this voice.
The Internet is enabling conversations among
human beings that were simply not possible in the era of mass media.
