1. Thank you for the great discussion.  I understand your point of view. Communication systems can also be understood in terms of the different media they employ. Some for example, are designed only for voice, whilst others may carry images or data. The value of one medium over another is usually context dependent. The nature of a particular task, the setting in which it occurs, and the amount of information that a medium can bear all seem to have effects on human performance on a communication task. For example, I noticed in one of my offices -relative information-lean media like electronic mail and voice-mail can be used for routine, simple communications. However, it seems that for non-routine and difficult communications, a richer medium like video, and preferably face-to-face conversation, should be used. What are your thoughts?

2. Do people prefer to use gatekeepers?
