We often use e-mail to get done quickly those things we are attempting. There can be problems. This item recently appeared in the Christian Science Monitor.
"The answer, the professors conclude, is sometimes "no." Though e-mail is a powerful and convenient medium, researchers have identified three major problems. First and foremost, e-mail lacks cues like facial expression and tone of voice. That makes it difficult for recipients to decode meaning well. Second, the prospect of instantaneous communication creates an urgency that pressures e-mailers to think and write quickly, which can lead to carelessness. Finally, the inability to develop personal rapport over e-mail makes relationships fragile in the face of conflict."
Next time you think of exploding on-line or think that you have just made an excellent point, take care.
