What you lose

I think this applies especially to 8/9/1 triad, all of whom have a tendency to black and white thinking, but it also has an application to a culture that is too linear and fundamentalist.

When you e-mail or tweet or text, here’s is what you lose:
Voice tone
Body language
Energy level
Facial expression
Pace of expression (how fast or slow the speech is)
Any touch

So if you have any nuances, exceptions, concerns or consequences you foresee in your text, you might consider actually talking face to face.
