My Age of Investment

  Chapter 192 Information Flow

   Facebook meeting room.

   Sitting under the stage were Evans and other technical backbones. Xia Jingxing wrote and painted on the big blackboard and said:

  "On the Internet, people obtain information through two main ways, editor recommendations and user active searches."

  Xia Jingxing wrote two words on the blackboard, "Reflected on the Internet model, it is portal and search.

  What we have to do now is to explore the third way-Newsfeed (information flow). "

  Evans and several technical backbones were confused. What is this?

The concept of    is relatively abstract. Xia Jingxing also saw the doubts in the eyes of a few people. Holding a marker, drew the realization model diagram of the information flow, and explained:

  “Originally, the user’s social interaction and information acquisition were to be combined with each scene, such as socializing with classmates in school, socializing with neighbors in the community...

  Information flow platform, you can aggregate all the scenes together, as an aggregator, fusing people, information and scenes together.

  This kind of passive instillation of information happens to cater to people's inertia.

  To describe it in professional terms, that is:

  According to the frequency of user interaction with users or information on social networking sites, algorithms are used to evaluate users' preferences for various content, and information is arranged according to the degree of importance, and relevant information in social networks is pushed in real time.

  This kind of push includes user status updates and personal information updates.

  For example, you have a friend named Jack, who uploaded a new photo and posted a new blog...

  All of you, you can see Jack’s change through Facebook for the first time, and give Jack a comment and like.

  Jack can also reply to you quickly, and everyone will interact together.

  Conversely, Jack can see all the changes you make on Facebook, and give you likes and comments.

  If the previous Facebook is "dead", what we have to do is to make him "live". Users can perceive the changes of the people they follow, every minute or even every second, and respond immediately.

  I call this kind of social networking "real-time", "interactive" or "onsite" social networking.

  The relationship between people can be maintained or even deepened through the social network of Facebook.

  Even if you and Jack have not seen each other for half a year, you can still follow each other's changes through Facebook. "

  Evans understood now, pointing to the model picture on the blackboard and asking: "Darren, do you mean to make Facebook's information flow faster and more timely?"

  Xia Jingxing nodded, that's what it meant.

  Evans hesitated, "Will users like this kind of information flow?

  For example, Jack secretly uploaded a photo of him going to a nightclub and kissing a certain beauty last night. He originally thought that no one would know about uploading it to the album.

  As a result, the next day, he got up and found that all his friends on Facebook knew that he went to the nightclub last night and had an affair.

  These people who know, also include a girl he likes. "

  Evans’s questions seemed very funny after more than ten years.

  But at the moment, everything is innovation, everything is groping, and it is normal to have concerns.

  Xia Jingxing smiled and said: “So I asked you to study it! We naturally respect the privacy of users. You can set a button and users can choose to make it public or not.”

  Evans suddenly realized, "In this case, it's okay. I think the other points are simply awesome."

  Ling Fan asked: “Dairun, can it be understood that the user’s homepage is no longer static, boring and useless, but a constantly updated “newspaper”.

   Presented to Facebook users are: things that happen on Facebook that we think you will care about. "

  Xia Jingxing smiled, "You use "static" and "newspaper" very well.

  In the future, Facebook will be dynamic, and there will no longer be only personal data pages on it.

  The information generated by users will be shared with other people to read and know like a "newspaper".

  Usually when people think of newspapers, what is their impression?

   is some editorial content. The editor decides what they want to say and what they want to print. They did this the night before, and then they distributed these articles to thousands of people.

  But as far as Facebook is concerned, we are building 10 million different newspapers because everyone has an extremely personalized version. "

  A veteran of the Evans team raised his hand and asked: "I feel that this is very similar to Juyou.com. Each of their users also has a personalized version!"

  Xia Jingxing shook his head again and again, "No, no, they just can edit the homepage freely for each user, it looks like a large website with independent small websites.

  Users have only colorful website homepages.

  This is just appearance!

  What we are going to do is the kernel. The life of each user is presented on Facebook, which is different and wonderful. "

  Evans said with some worry: “If you want to realize the frequent interaction of tens of millions of people on Facebook, the amount of engineering is probably not small, and the amount of data that needs to be processed is also on the order of days.”

  Ling Fan added: “Not only that, we also need to study how to convey what users care about most. Is it pictures or text, and how much weight do they occupy?”

  Xia Jingxing stalled, "I can't help it, and I didn't ask you to develop it immediately.

   is just to propose a direction, the specific design plan still needs you to improve one by one. "

  "Perhaps it is possible to build a distributed system?"

  Some employees put forward ideas under the stage.

  Evans immediately shook his head, "Too avant-garde, and the amount of engineering is quite huge."

  Xia Jingxing’s eyes lit up, and he smiled and said, “Don’t put too much pressure on it, try it boldly. I think a distributed system is great!

  In short, the company will do its best to help you complete this development task. "

   "For the specific situation, we have to discuss with the engineer team and thoroughly research all the technical points before we can give a detailed development plan."

  Evans looked at Xia Jingxing, even he is still a little confused now, the product idea of ​​information flow is clear, and the achievable path, code, and logic need to be carefully considered.

  Xia Jingxing nods slightly, he is not very urgent, because this information flow technology is not mature now.

  It wasn't until 2006 that Twitter brought this technology to the forefront for the first time.

  But Twitter is mainly about dissemination of information. Information dissemination is one-way, similar to Weibo. Information spreads faster. You can follow someone and see the other party’s updated information at all times. The relationship is information service.

  Facebook is based on a two-way mechanism of adding friends to each other. The circle is more private, similar to QQ space, and information serves the relationship.

  Xia Jingxing then drew the model diagram on the blackboard, the second product-graffiti wall.

  He pointed to the blackboard and said: “It is necessary to develop a function that is compatible with the information flow. Users can freely post text, photos, and links on the graffiti wall, which can be to share feelings or express opinions on things.

After    is released, it will appear in the dynamic column of the user's friends, and all friends can see the information posted by the user in real time, and give comments and likes. "

  This function is actually the "personal dynamics" in Qzone and WeChat Moments. There is no similar product on the market.

  The product is not complicated. Everyone here understands it. Evans asked: "This is a bit similar to our upcoming blog? Is there a limit on the number of words?"

   "Yes, the blog posts a long article, this is a short article, just understand it."

  After Xia Jingxing finished speaking, all the employees present nodded their heads. If they were distributed in this way, it would not be considered a product conflict. Not everyone would write a blog. This kind of short essay is undoubtedly more popular with users.

  Xia Jingxing thought that after the launch of these two functions, the prototype of Facebook's previous life basically came out.

  From Xiao Mazi, I wonder if there will be any new tricks?
