A quick snippet of someone whose presentation gave me some awesome information to walk away with and feel super smart (therefore, Khoi Vinh rocks 'cause he's brilliant and he presented the information in a way I can use it to feel smart):
"Most features are for experts, but most users are intermediates."
Yep. Remember that. Even when designing presentations.
Sure, there were probably a few people in the audience who went, "Bah. I already knew that. Tell me something I haven't heard before." But Khoi presented for the rest of us who needed to hear that, which made him one of my highlights. :)
