Kuttner does make some very observant points about e-mail. In an e-mail, tone cannot be understood the exact way a person intends it to be read. Kuttner describes an incident with a friend where insults were exchanged because of a misconception of a tone in the e-mail. This can very easily happen when exchanging e-mails, but this can also happen on the phone or in person. Tone can be understood in many instances. It all depends on the relationship between the two individuals interacting. Also, Kuttner points out how public and exposed e-mails can be. Yet, people need to use their discretion in any circumstances when divulging important personal information, not just through e-mail. Kuttner forgets that human discretion is a major part in the use of e-mail.
