I went back and looked at the applications for the current cycle, and roughly half the groups we invited to interviews tied for the highest grade from Rtm. Which was a B+.
Do you think you could make this data public, maybe starting off with startups that didn't make it, including YC's comments when they were evaluated during the interview?
I am sure there is a lot of great info in there that would help other startups. It would be like using etherpad for writing essays :-), we could peek into YC's thought process.
