1, Baidu knows that it is a divergent structure, and Zhihu Q&A is a convergent structure. Theoretically, anyone can see the problem you throw into Baidu, but you can't see it on Zhihu. If seeking an answer is sometimes like looking for a needle in a haystack, it is more likely to be found on Baidu Know than Zhihu Q&A.. But if your question is just right, you will gain more from Zhihu's question and answer than from Baidu's knowledge.
2. Baidu knows that it is a bounty killer mode, and Zhihu Q&A is a discussion mode. Baidu knows that the mode does not encourage in-depth discussion, and the question-and-answer relationship is simple and direct, but it lacks the expansibility of Zhihu's question-and-answer. The discussion mode encourages more interaction, and the question-and-answer process will bring more inspiration and thinking.
3. Baidu knows it's fast food, and Zhihu's question and answer is private cuisine. Eating enough is the only pursuit of the former, but not the only pursuit of the latter. Whether the food has been praised, whether it has happened in eating and drinking, and so on. It may be more important than eating.
4. Baidu knows that the participation threshold is low, while Zhihu's question-and-answer participation threshold is high. You can't expect a middle school student who can't do problems to register for a Zhihu Q&A to ask questions, but he can go to Baidu to ask questions at once.
