pros and cons of cyber communication

In chapter 14, we see the positive and negative implications of cyberspace communication explained thoroughly. I think that cyber communication such as e-mail as well as instant messenger bring are easy to use, but neglects certain aspects of communication. Although email is very easy and straight forward, it totally lacks physical information, and the person reading the email does not have any idea of that person's emotions or facial expressions as you would see in a face-to- face situation. This type of communication narrows human relationships, because an individual can have a totally different relationship on the internet, and can carry themselves totally different electronically than in "real" life.
