During the Q&A, Poole answered a question from one of the masked employees. After his answer, he asked, "Did that help, Steve?" Shocked, and no doubt a bit intimidated, the employee asked how Poole knew his name. His answer: "Well, I read your name on the badge clipped to your belt."
Poole was smart and thoughtful and I was quite impressed (not just with his eye for detail). Not surprised he lasted so long at Google.
