Robert Steele was lead off/keynote speaker at Gnomedex. Former intelligence officer with the Marine Corps and the CIA. He argues that U. S. intelligence reform is needed and that the private sector can perform a high percentage of U. S. intelligence needs. Scary stuff (PDF).
Guy Kawasaki boiled his thoughts on "Evangelism" down to ten (eleven?) very powerful points.
I assume the video of these two presentations will be online and I’ll link. I wouldn’t even begin to summarize or comment, beyond encouraging you to watch/read. These two speakers worth the trip.
