Abstract:

Internal communication isn't generally seen as a direct, short-term contributor to the bottom line, and therefore it is not considered "hot." More to the point though, people's understanding of what communication is and how it can work is extremely varied and often plain wrong. It seems that what makes internal communication "hot" is still mainly understood only in professional communication circles.
