Neither. In our class (S12), there were founders from every background imaginable. I also know founders from other classes, and the same is true amongst that sample. If anything, YC founders seem a bit less "credentialed" than the Valley in general.
To the extent that "name-brand" universities tend to graduate extremely smart, capable people, you'll find that they're over-represented in any sample of smart, capable people. But YC has no incentive to select for factors that don't correlate with outcome.
I might suggest that if you're encouraging people to study/memorize the names for YC interviews, you provide a downloadable/clippable version, that they can paste into standard flashcard tools.
2- You're loading Zepto externally through cloudflare, but calling it as an inline script. This is causing an issue where Zepto can't initialize, as the external JS hasn't loaded yet. There are a number of ways to fix this, but it renders the site unusable in chrome for me (Although it works in other browsers)
And there are a couple more YC employees usually present, handling scheduling and logistics.
