Thinks s/he gets paid by the post
I find in matters of fact, an email (or post in a forum) is most efficient. When asking a question an email has the documentation of both question and answer. But in many situations, if you need to personally know if the other party has seen or read your message, such as a plan to meet tomorrow for dinner...... a phone call is best. Further, in matters of 2 way negotiations, gives and takes, finding the best option of 2 offerings, emails are terribly inefficient at the beginning. The telephone is great for this. An E-mail works wonders to document the agreed upon points of the phone conversation. There are times when one is better than an other.
