Paul is right...but he hasn't gone far enough with points 1 and 2....

Business is a talk show! All talk shows have a host.

This is a usable metaphor. In fact, Fast Company magazine used this very idea as a cover story in 1999...placing David Letterman and Oprah Winfrey on the cover....discussing how informal conversations create vectors of influence...and that leaders understand that and encourage it.

Leadership-as-host is good. "Boundaryless" connections are good. "Business-as-talk show" is great because it's so true.
