Because I have this need. The following is a personal analysis.
Advantages:
First of all, for the questioner:
1, attracting the attention of respondents more efficiently.
Second, for the interviewees:
1. Respondents can not only get psychological rewards of praise, but also get substantial benefits.
2, substantial benefits, can enhance the enthusiasm of respondents.
3. Give (or explore) some respondents who are not in this professional field but have this potential specialty and are unknown or even self-aware, get a chance to answer and get a reward. However, if the paid question only supports asking questions to a certain user, it does not have this advantage.
4. The higher the reward income, it is also an affirmation of the quality of the answer, which has a positive stimulating effect on the answer.
Third, for the onlookers:
1, free reading and paying for quality answers.
Disadvantages:
1. Answering for the sake of answering is easy to produce a large number of inferior answers. However, this seems to be self-purification, and inferior answers will eventually be covered up by high-quality answers.
2. There is no objective standard of advantages and disadvantages, which will easily lead to disputes between right and wrong and affect harmony.
3. Too many respondents focus on finding questions with economic benefits, which will weaken the attention of some public welfare questions and answers. Can setting specific fields before paying questions eliminate this problem?
4. The popularity of paid questions may quickly lose attention after being divided into rewards. However, the problem of non-payment will also lose popularity after it becomes popular. This feature is not unique to the payment problem? Not a shortcoming?
5. Questions and answers aimed at money gains may adversely interfere with the purity of questions and answers.
