Being one of the no idea / barely an idea teams in s12, one of the teams that acrimoniously blew apart and probably one of the teams that led to the changes that YC made for w13, I am glad that "no idea" is no longer an option.<p>I still view YC's willingness to experiment in an extremely positive light. It's why YC is the innovator, and everyone else (500, techstars etc) are just imitators. That being said, I think "no idea" was a bad idea, for YC as investors and advisors, for the following reasons:<p>1. It created teams that had not actually <i>worked together</i> for a significant length of time on an idea that <i>all founders believed in</i>. In other words, "teams" which were not actually "teams", but rather a set of individuals with strong credentials.<p>2. Some of the most important psychological benefits of going through YC, particularly the artificial pressure of Demo Day, have a paradoxical effect on "no idea" teams. The experience of watching good startups grow literally before your eyes at weekly dinners is inspiring, but not particularly conducive to coming up with your own idea. For me at least, it created an almost existential angst.<p>3. Without an idea, a shared revolutionary vision of the future, there is nothing binding a team together. Each time an idea "failed" there was an intense feeling of loss and personal failure, particularly (as mentioned above) when you see the "idea" teams progressing week on week. That emotional baggage can rip apart formerly great friends .. it did in our case.<p>Given that, s12 was <i>not a disaster</i>. For one, many s12 teams are doing brilliantly, and I wouldn't be surprised if there are more than a few black swans amongst my batchmates. But more importantly, it wasn't a failure in the same sense that Edison's first 9,999 light bulbs (that didn't work) were not failures.<p>For me personally, "no idea" was a great idea, as I learned more from my YC experience than can be quantified. While I'd never take funding again without an idea (or a working product or service) as it causes unnecessary and often contradictory pressure, my understanding of how to succeed in startups is orders of magnitude greater than it would have been without YC, and for that I will be eternally grateful.
