I'm going to risk being labelled a fanboy for mentioning Seth Godin twice in as many days but was just sent this 12 minute interview that is really worth a watch. The interview covers off a broad range of topics including building a tribe, creating a cult product, permission marketing and even our individual responsibility to act as true leaders in the name of  positive change . His comment on choosing between being a wandering generality vs a meaningful specific made me smile.  Could possibly have been chagrin though.
