This was a freaking awesome session!
Prof David Ng (born 20 days after me) is an engaging speaker.
One Great Thing: popularizing science through one of the most innovative uses of crowdsourcing I have ever seen. Very elegant web interface as well - Phylo: The Trading Game
One Suggestion: Hard to think about one again! But, perhaps picture of pool on box and picture of pool in reality might have been more effective on 2 different slides?
I would watch for the video of this session folks. Really five star all the way!
