The vertical social interaction I understand has social scope. For example, we pull a group on WeChat, and the group is full of processes. The chat content is probably not going to stocks, funds, futures and precious metals. I have seen a website before that is close to my understanding of the concept of vertical social interaction, and its content form is similar to that of Weibo. Generally speaking, it is like this: If I see a good product on Taobao/1 Store/Tmall/JD.COM. The computer outputs microfilm ..., and then I copy the address of the product and post a message. Then the website will automatically collect the data of this product to form a "Weibo", and then I can make an evaluation or recommendation on it and post it. Then you can see the goods shared by your friends, and then you can comment and forward them. The key is that it can only send this, which is equivalent to a private circle mushroom street. Unfortunately, I forgot the name of this website. Personally, this kind of vertical socialization is not desirable, although the content is specific and professional. There are three reasons: 1. Users have a wide range of interests and tend to be comprehensive. Can you do content and socialize vertically? Do you want them to talk about a topic and turn to social platforms? 2, lack of content. What a person can provide is limited in quantity and quality. If the circle is restricted, it will inevitably lead you to get this information. Why can you only get this information online, even vertically? The more information users want, the better. If you have more, you can filter useful information. If you are short, you will only waste time. It doesn't matter whether this social interaction exists or not. 3. User viscosity is a problem. Generally, vertical websites will only be used when users need them, and users spend most of their time on comprehensive social interaction. For example, users can talk wildly on Weibo, from finance and economics to politics, from politics to literature and art, from literature and art to art. ... if a social platform dies and you can only talk about the content in one direction, then the time users spend on it can only be limited.
