"Thanks @Jimmy Wales for the invitation. As the founder of Quora, I thought it was necessary for me to answer this question.
The channels for people to obtain knowledge are constantly increasing. They first obtained knowledge from teachers, and later from books. In modern times, we increasingly rely on obtaining knowledge from the Internet, such as search engines.
After founding the Riot Electronics Community, I saw a large number of posts on it with players’ various questions about the game, such as which race is the strongest in the StarCraft section, and what is the best start for each race? .
Including our launch of "Plants vs. Zombies", newcomers often ask questions, hoping to know how to configure plants to successfully pass some difficult levels.
So I came up with an idea, that is, can we create a community that focuses on answering questions, so that everyone's knowledge can converge here.
When I came up with this idea, I had to choose partners. I had other companies and didn't have the energy to do this. At that time, I heard that there were people in Silicon Valley who had similar ideas to me. This person was @Jimmy Wales and @Lawrence Sanger.
They tried to build an online encyclopedia, Nupedia, to solve this problem, but Nupedia's progress was slow. When I found them, after hearing my idea, they thought that the trivia community was a better solution than an online encyclopedia. solution to this problem.
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 follow specific topics or other users.
Our feature is that users can vote, comment and edit answers to ensure that high-quality content is seen by more people.
And Quora has strict community guidelines and management measures to prevent abuse and spam. With the example of Riot Electronics Community in front of us, everyone can fully believe in our ability to manage a high-quality community.
Finally, I hope everyone can have a good time here. "
Zhou Xin's answer received hundreds of likes, making it the most upvoted answer to this question.
Robin thought it was very creative, "It's Newman's idea again. Under the questions, you can choose to sort by the number of likes or answer time, which not only allows users to see high-quality answers, but also allows users to see the latest answers.
The design that takes both into account is clever enough. "
Jimmy Wales and Lawrence Sanger mentioned by Zhou Xin in his answer should have been the founders of Wikipedia.
They are working on the predecessor of wiki, Nupedia Encyclopedia, which is a purely academically oriented online encyclopedia, all written by experts and scholars, and must undergo strict review and review after writing.
Nupedia can be seen as a journal with lower thresholds, and because of this, this work is progressing very slowly.
Jimmy Wells and Larry Sanger felt frustrated and doubtful. After Zhou Xin found them, the three hit it off. The trivia community was not only able to achieve what they wanted to do, but also had higher commercial value.
As for the two of them who knew Zhou Xin's idea, they would leave Zhou Xin to work on it themselves. Not to mention that Quora's website framework and beta version had already been built, and they would be far behind in time if they worked alone.
Zhou Xin's reputation in Silicon Valley alone has never failed since he started his business, and his valuations are all in billions of dollars. Moreover, Zhou Xin has a good reputation in Silicon Valley and is willing to share shares. Whether it is the earliest Ashley and Stephen or NewPay’s Feng Lewis and Warren Jensen, they all received shares.
In addition, Quora's direction overlaps greatly with online encyclopedias, so Jimmy Wells and Larry Sanger agreed to join Quora without hesitation.
For Zhou Xin, not to mention the fact that the two founded Wikipedia, the fact that they were able to start Wikipedia has fully proved their management capabilities.
Originally, Zhou Xin also planned to package Online Encyclopedia and Quora into a company, and the users of these two would be the free labor force of Online Encyclopedia.
What's more important is that the two of them worked on Nupedia before and accumulated a lot of connections in academia.
The academic leaders Zhou Xin knew were all concentrated in the field of integrated circuits. The two of them were different in that they knew academic leaders in all fields.
In addition, Larry Sanger set up a mailing list server during his college years to establish a communication platform for students and tutors who need tutoring, thereby establishing a forum to provide personalized tutoring courses and personalized tutoring methods.
Through this service, he also has a certain influence among college 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 tycoons in Silicon Valley.
Let's return to Robin. As a master's degree in computer science from the State University of New York, Robin was very concerned about technology in his early days. After he entered the computer field, he discovered that there were all kinds of problems.
"Why is the DSL service model faster than the traditional dial-up connection?"
"I am a freshman majoring in computer science, but I don't feel any fun from computer learning. What should I do?"
Of course, there are also very professional questions, such as "What are the advantages of the PageRank algorithm?"
“The PageRank algorithm provides a new way of thinking for search engine ranking algorithms.
When designing this algorithm, we mainly considered the quality and quantity of links, and used the relationships between these links to build a link graph between web pages to rank web pages.
We assign a numerical weight to each element of a hyperlinked document set, with the goal of "weighing" its relative importance within the set. This 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, denoted PR(E).
PageRank is derived from a webgraph-based mathematical algorithm created from all World Wide Web pages as nodes and hyperlinks as edges, taking into account authoritative centers such as or mayoclinic.org. The ranking value indicates the importance of a particular page. Hyperlinks to pages count as support tickets. A page's PageRank is defined recursively and depends on the number of all pages linking to it ("incoming links") and the PageRank metric. Pages linked to by many pages with high PageRank will themselves rank highly..."
This answer was quite professional. Robin looked at the answerer's ID, Sergey Brin.
Colleagues are enemies, Robin knows each other, they are all engaged in search engines, and their PageRank algorithm is very similar to the algorithm he invented.
The site scoring algorithm Robin developed for IDD was the first algorithm to use hyperlinks to measure search quality.
Robin couldn't help but write an answer below: "PageRank can learn from the Rankdex site scoring algorithm..."
