I got the chance to attend this year and what struck me as most interesting about the weekend was not the day of speakers but the people I met. I meet lots of people who talk about startups but almost everyone I met was deeply serious and wicked smart. Every person I met, every conversation I had I came away thinking that they would be successful...and I am usually quite pessimistic in that scenario. Ground zero is a great term, I feel I met so many great people and heard so many great ideas that there was almost certainly a unicorn company in that room.
