Chapter 74 Robin’s first experience with Quora (seeking for further reading))

"Thanks @Jimmy Wales for the invitation. As the founder of Quora, I think it is 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 the enduring post on StarCraft, which race is stronger, and how each race starts the best way.

.

Including the "Plants vs. Zombies" we launched, 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 I create a community that focuses on answering questions, so that everyone's knowledge can be exchanged 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 Electronic Community in front, everyone can fully trust 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 thinks it's very creative, "It's Newman's idea again. At the bottom of the question, you can choose to sort by the number of votes 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 consideration is clever enough.”

Jimmy Wales and Lawrence Sanger mentioned by Zhou Xin in his answer were supposed to be 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 regarded as a journal with low threshold, and because of this, the progress of this work is very slow.

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’s reputation in Silicon Valley is very good, and he is willing to share shares, whether it is the earliest Ashe

Lee, Stephen, and NewPay’s Louis Von and Warren Jensen all received shares.

In addition, Quora's direction overlapped 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 build 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.

More importantly, the two of them had previously worked on Nupedia and had accumulated a large number 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 from all fields.

In addition, Larry Sanger established a mailing list server during his college years to establish a communication platform for students and tutors who need tutoring. This established 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 DSL service model faster than 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 relationship between these links to construct a link graph between web pages to rank web pages.

We assign a numerical weight to each element of a set of hyperlinked documents with the purpose of "weighing" its relative importance in the set. This algorithm can be applied to any set of entities that have mutual references and references. It assigns to any given

The numerical weight of element E is called the PageRank of E, expressed as PR(E).

PageRank is derived from a mathematical algorithm based on webgraph, which is created from all World Wide Web pages as nodes and hyperlinks as edges, taking into account or equal authority centers. The ranking value indicates the importance of a specific page. Hyperlinks pointing to the page 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. A page linked to by many pages with a high PageRank will itself receive a high ranking."

This answer is 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 developed by Robin 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."

The release date will be either this Friday or next Friday.
