Although there are always people who want to find a propagation law according to Zhihu's popular answers and try to create new artificial hotspots with this law, there is basically no law to follow in the current hot items. Zhihu still retains the excellent quality that only "dry goods" will be popular in most cases. The only exception worth discussing is in the emotional field. No matter what you take as your major, you are willing to discuss it in the emotional field. There is no so-called expert authority in this field. Therefore, no matter how professional some people in other fields are, it is possible that the quality of answers to emotional questions is similar to that of "three no users". Therefore, the number of praised answers may only depend on the popularity of the respondents themselves. For example, we often see some questions. The questioner shows strong male chauvinism, narrow-mindedness, preference for sons over daughters, strong jealousy, or other bad characters. This problem usually boils down to the field of "this kind of person actually has a boyfriend/girlfriend". At this time, the attention and answers of several big V's will make this question suddenly fire up, and you will expect to see long answers from new users and "anonymous users" about their personal experiences later. As for what big V is going to do at this time, maybe one sentence is enough.
