Gary--Both Laura and Michelle made one of the points that came to me after reading your thoughtful post. I value my IABC membership because of the diversity of its membership. The other point is that I see how the organization in which I work (my day job) could be much more effective if its various communication silos [e.g., Marketing, Public Relations, Corporate (internal) Communications and Social Responsibility] worked together. Some professional associations may be myopic, but hugely positive change could be made elsewhere by giving organizations a new pair of glasses.
