No prizes for guessing that the undisputed high of all time highs was the Doris Kearns Goodwin - keynotes really don't get any better than this. Sadly it looks like the session won't go online so here are the next best things I can manage:
YouTube video of her being interviewed about the book - not quite the same as the keynote but close enough to get an idea: http://www.youtube.com/watch?v=_N3eU2UsYio
book available at: http://www.amazon.co.uk/Team-Rivals-Political-Abraham-Lincoln/dp/0743270754/ref=sr_1_5/202-5724948-5678257?ie=UTF8&s=books&qid=1193703767&sr=8-5

The Lincoln leadership lessons (borrowed from a book review rather than session notes - hence more articulate than I might usually manage):
1. Surround yourself with whatever talent the given enterprise requires.
2. Welcome, indeed strongly encourage principled dissent.
3. Timing is not everything but often the difference between success and failure.
4. Exercise selective hearing during a contentious group discussion.
5. Unless absolutely certain, be willing to grant benefit of the doubt.
6. Exhaust opponents by listening to them.
7. Appreciate effort but only reward performance.
8. Serve “with malice toward none, with charity for all”
9. And lead “with firmness in the right.”
10. When dealing with forceful personalities, focus on common interests.
