** "Jessica's 2007 book" ✔ ** "it may be worth adding a row on how Paul Graham defended Airbnb as nice ppl when there was a controversy" ✔ ** Row for openai mentioning Sam Altman too, who is more Central to openai than Jessica ✔ ** Maybe a few rows on the pre-YC life of the key partners, esp. Paul Graham and Jessica Livingston ✔ ** Row for Sam Altman joining as a YC partner? ✔ ** The launch of Hacker News (news.ycombinator.com) and more information on its role in the Y Combinator ecosystem ✔ ** Row for Y Combinator batch that had Reddit ✔ ** Row for Quora being a late YC joiner ✔ ** You mention that ACLU is a YC consultant but not that ALCU joined the YC batch as a nonprofit too ✔ ** More on nonprofits that joined YC (80,000 Hours, Centre for Effective Altruism) ✔ ** Imagine K12 ✔ ** Rows for competition? i.e., other startup accelerators that have similar models, or models that are different in some key ways ✔ ('''I only included three accelerators as competitors. I'm planning to go deeper in the subject in the [[Timeline of startup accelerators]]. Let me know if you want more discussion on competition on this timeline''').
** Y Combinator's release of application videos ✔ at https://www.ycombinator.com/video/ and there's also a fuller list at https://mittalrohit.com/59-links-for-y-combinator-application-and-interview-advice-bf90191be8ed ('''Most of the rows under Advice for startups type of event come from sources given in the latter link''').
** '''I included a row for each school batch except the ongoing Winter 2019. I think I named all the non-profits. I named also the top rated YC companies according to valuation [https://www.ycombinator.com/topcompanies/], and others with article on Wikipedia'''.
