"Thank you @Jimmy Wales for the invitation, and as the founder of Quora, I thought it was necessary for me to answer this question.

The number of ways people have access to knowledge is increasing, first from teachers, then from books, and now we are increasingly relying on the Internet to obtain knowledge, such as search engines.

After starting the Riot community, I saw a lot of posts about the game, such as which race is the strongest in the StarCraft board, and how each race starts the best game.

Including our "Plants vs. Zombies", there are often newcomers who ask questions, hoping to know how to configure plants in some difficult levels to successfully pass the level.

So I came up with the idea of whether we could create a community focused on answering questions, where people's knowledge could be exchanged.

When I came up with the idea, I had to pick a partner, and I had other companies that didn't have the energy to do it. At that time, I heard that there was someone in Silicon Valley who had similar thoughts to me, and that person was @Jimmy Wales and @Lawrence Sanger.

They tried to build an online encyclopedia, Nupedia, to solve this problem, but Nupedia was slow to make progress, and when I found them, they heard my idea and decided that a quiz community was a better solution to the problem than an online encyclopedia.

So after the two joined, Quora's development entered a fast lane.

Users can ask questions, answer questions, edit and rate questions and answers on Quora, and also follow specific topics or other users.

We feature users who can vote, comment, and edit answers to ensure that high-quality content is seen by more people.

Quora has strict community guidelines and governance measures in place to prevent misuse and spam. With the example of Riot's e-community in front of you, you can fully trust our ability to manage a high-quality community.

Finally, I hope you can have a great time here. ”

Zhou Xin's answer received hundreds of likes, making it the most upvoted answer under the question.

Robin thinks it's creative, "It's Newman's idea again, and you can choose to sort by number of approvals or answer time at the bottom of the question, so that users can see both high-quality answers and the latest answers."

The design that takes into account both is clever enough. ”

Jimmy Wales and Lawrence Sanger mentioned by Zhou Xin in his answer were supposed to be the founders of wikipedia.

They were working on the wiki's predecessor, Nupedia Encyclopedia, a purely academic-oriented online encyclopedia, written entirely by experts and academics, and subjected to rigorous review and proofreading.

Nupedia can be seen as a journal with a low bar of entry, which is why the work is progressing very slowly.

Jimmy Wells and Larry Sanger felt frustrated and skeptical, and after Zhou Xin found them, the three hit it off, and the trivia community was not only able to achieve what they wanted to do, but also had higher business value.

As for the two of them knowing Zhou Xin's idea, they will throw Zhou Xin to do it themselves, not to mention that Quora's website framework and beta version have already been made, and they are also lagging behind a lot in terms of time.

Zhou Xin's fame in Silicon Valley alone has never failed since he started his business, and his valuation is all in billions of dollars. And Zhou Xin has a good reputation in Silicon Valley and is willing to share shares, whether it is the earliest Ashley, Stephen or NewPay's von Louis and Warren Jensen, they have all been shared.

In addition, Quora's direction overlaps with the online encyclopedia, so Jimmy Wells and Larry Sanger agreed to join Quora immediately with little hesitation.

For Zhou Xin, not to mention the fact that the two founded Wikipedia, they have fully proved their management ability from being able to build Wikipedia.

Originally, Zhou Xin also planned to package the online encyclopedia and Quora into a company, and the users of these two are the free labor of the online encyclopedia.

What's more, the two of them have accumulated a lot of academic connections in Nupedia before.

The academic bigwigs that Zhou Xin knows are all concentrated in the field of integrated circuits, and the two of them are different, and the academic bigwigs he knows are all over the field.

In addition, Larry Sanger ran a mailing list server during his college years to establish a communication platform between students and tutors in need of tutoring, so as to establish a forum to provide personalized tutoring courses and personalized tutoring.

Through this service, he also has a certain influence among the university students.

Zhou Xin's plan for Quora is that the initial users will be mainly students and university professors, followed by Internet practitioners and Internet bigwigs in Silicon Valley.

Looking back at Robin, as a master of computer science from the State University of New York, Robin was very concerned about technology in the early days, and after he entered the subdivision of computers, he found that there were all kinds of problems in it.

"Why is the DSL service model faster than the traditional dial-up method?"

"I'm a first-year computer science major, but I don't get any pleasure out of computer learning, what should I do?"

Of course, there are also very technical questions, such as "What are the advantages of the PageRank algorithm?" ”

"The PageRank algorithm provides a completely new way of thinking about search engine ranking algorithms.

We designed this algorithm with the quality and quantity of links in mind, and used the relationship between these links to build a link graph between web pages to sort web pages.

We assign a numeric weight to each element of the hyperlinked document set, with the goal of "gauging" its relative importance in the set. The algorithm can be applied to any collection of entities that have mutual references and references. The numerical weight it assigns to any given element E is called E's PageRank, which is denoted as PR(E).

PageRank is derived from a mathematical algorithm based on a webgraph that is created from all World Wide Web pages as nodes and hyperlinks as edges, taking into account authoritative centers such as or mayoclinic.org. The rank value indicates the importance of a particular page. A hyperlink to a page counts as a support ticket. A page's PageRank is defined recursively and depends on the number of all pages linked to it ("incoming links") and the PageRank metric. Pages that are linked to by many pages with high PageRank will themselves get high rankings......"

The answer was quite professional, and Robin glanced at the respondent's ID, Sergey Brin.

Peers are enemies, Robin knows each other, everyone is engaged in search engines, and their PageRank algorithm is very similar to the algorithm he invented.

Robin's site-scoring algorithm for IDD was the first to use hyperlinks to measure search quality.

Robin couldn't help but write the answer below: "PageRank has a place to learn from the Rankdex site scoring algorithm......"
