1) Testing PG's Top Ten Things That Kill Startups - co-founder problems, fundraising, etc. 2) Is this biggest mistake usually that people don't fire fast? 3) We know the unicorn growth rate - but what is the median/average growth rate for a semi-successful YC company? 4) What makes a company part of the walking dead? 5) What are the primary channels a lot of YC companies use for user acquisition? How has that changed? 6) What are the primary reasons for rejection for YC companies? Does it differ by partner or uniformly the same? 7) We know that airlines are hard. It'd be great to see what specific categories of startups that YC has funded that are just more difficult to grow in or are easier to get traction in - e.g. consumer v. enterprise, analytics, gaming/media? 8) In fact, I'd love to see a review of PG's claims in general either backed by data or refuted by data. I suspect they're backed by data, but it'll likely give more insight into the key area that people find interesting. For example, are more people now finally choosing NOT to go to grad school?
