From the intro on the newish site:
The aim of this Club is to gather CEOs who believe in the blogosphere and its extraordinary potential and to offer them a place to share with other companies leaders the experimentation they are conducting thanks to weblogs. Corporate blogging, CRM, marketing, PR, internal communication, are part of the different ways blogs are being used today, but as we all know, we are only at the beginning. And who is able to say how weblogs will affect our business tomorrow?
Could be interesting to watch. The site owner is based in Europe, but it is meant to be an international resource.
