Hi, Kenneth - thanks for the comment AND the book suggestion (as though I need another title to add to the list:).

Coleman's book sounds very interesting and I look forward to reading it.

I really like your observation that those who work internally are taking a great risk - this is how we flip people's thinking to show them different ways of thinking.  I often engage with my friends who either still work internally or are frantically trying to "get back in" and you are right - they are eliminating a multitude of possibilities by focusing on a perceived security that frankly does not exist now, if it ever really did.

Appreciate your comments:)

John
