Additionally, Paul, thanks for being frank and great. It makes me so happy to see you as the face of not only YC, but increasingly of tech startups in general. When I get around to implementing a good idea, I've got you to look to not only for interesting me in programming through Lisp, startups through YC, but also for increasingly the visibility and viability of tech startups.
Definitely worth watching all 14 minutes.
EDIT: Also, still a little bitter over "the real money's in hotel search"… dzoblin's & my Summer '11 (I think) YC application was that. Though admittedly not far along, and the idea was still in development. still ;)
