On February 13, 2021, I paid 5 yuan to submit a question. As of February 15, 2021, there have been 11 answers. The official will notify you by private message to remind you of the progress of the problem.

Users are very active in the question and answer questions, and they have already adopted what I think is a good answer. Here are other users' suggestions and opinions on the question-and-answer function:

Five, product comparison

1.stackoverflow

As the world's largest technology question and answer website, stackoverflow can be said to be a must-visit website for everyone who has done technology.

Entering the question and answer interface as shown above, the left side is related to some label categories, and the middle part displays the questions on different labels, which is concise and clear.

The competitive advantage of stackoverflow is mainly the quality of questions and answers, and the quality of questions. It has established an evaluation system that effectively motivates participants through prestige and badges, allowing users to participate in it.

Because stackoverflow is all in English, questions and answers need to be in English, and the threshold is high.

stackoverflow does not pose too much threat to CSDN in China. CSDN mainly relies on blogs, and the Q&A function mainly increases the degree of adhesion with users.

A few points that CSDN can learn: For users who are more active and willing to answer questions, they can also provide virtual medals and special certificates. In the high-end direction, it is still necessary to polish the quality of questions and answers.

2. Think No

Sifu's reward and punishment system is very similar to stackoverflow, but I think the badge is not as good-looking as CSDN's (haha)

Most of the questions about thinking are concentrated in the front-end and back-end fields, and most of them are raised by in-service personnel. Some students in school have less programming problems.

I think a better point: after selecting the question label, he will push related articles and encyclopedia links (as shown above) , providing information on solving the problem

Due to the huge user base and reward mechanism of CSDN, the number of questions in the Q&A function and the activity of users are higher than those of Sifu.

Conclusion: a) Strongly not recommended b) Not recommended c) Fair d) Good, good e) Highly recommended

Choice : d) good, good

Reason : CSDN's question-and-answer function has a wide audience, and its radiation area (especially students) is very large, just domestically. Very innovative, fast problem solving time, high user activity, I think it is good, but there is still room for improvement.

7. Suggestions for improvement

1. Ask questions

The function of answering questions: Q&A VIP, 50 experts answering questions within 24 hours, 50 Q&A services, you need to open the original price 199, the limited time discount service of 7 yuan, which is equivalent to 4 yuan per question

This function is placed in a very obvious position in the question and answer module. Users who have opened VIP can make their own questions a separate module. If this question is answered by someone other than an expert, will the money be distributed to the person who answered it? , but the official received the money from the Q&A VIP. And the bounty is adopted after the answer to the question, which is profitable. This was originally to be solved by the experts in your site, and you distributed it to the users, which greatly took up the public space.

I don't know how much this member sells (if it makes a lot of money, I didn't say it, it can be kept). I think this function divides the connection between users. If you want to do a good question and answer community, this function is not recommended to be saved.

Solution : It is difficult to make users spend so much money at one time (you can ask questions again and again), the official can choose 50 or more high-quality answerers in different fields to allocate exclusive fields, and let users spend money to pay people in specific fields Ask questions and make sure that the question is answered and that the answer is accurate.

2. Waiting for your answer

This functional module is well done, and the official can answer some questions based on the blogger's area of expertise.

But I mainly know about algorithms, front-end, and programming languages. However, some server, database, and java related issues are recommended for me below. The matching mechanism can be improved.

3. Remuneration distribution

Adopt the answer distribution mechanism : 80% of the question remuneration will go into the account of the adoptee , and 20% of the question remuneration will be used as the platform's reward fund.

Problem : A problem cannot have only one solution or idea, and giving all the remuneration of the problem to the adoptee seems unfair to other people who provide different solutions and also help. It is suggested that 2 or 3 adoptees can be set up for a question, and the remuneration can be distributed reasonably.

The system automatically concludes the question : about 50% of the remuneration, the system will allocate the remuneration to the answerer proportionally according to the answerer’s Force level and the quality of the answer. What is the relationship between the answer to a question and the Force level, it should not Does the quality of answering the question matter?

4. Solve the keys

Look at the essence of the question above, why the accepted answer has not solved the following ridicule.

Why can a person who has no exposure to this field and has no doubts about this problem also click a solve button for other answerers

You can limit only experts in related fields, questioners, questioners of similar questions... to click to solve, for others, you can set an additional like button, if you think this answer is very interesting, you can like it, and this setting can also be Prevent others from maliciously brushing the number of solve buttons

5. Answer the questions

The text of the answer to the question should be related to the content of the question, and if it is not relevant, increase the review force

A person publishes multiple answers, which one is adopted, how to distribute the remuneration for automatic conclusion?

It is recommended to limit the number of answers, which can be modified in the answers you posted before

Experts have too much interest in answering questions, which greatly affects user enthusiasm and the quality of answers

Since the questioner has a certain template, does the answerer also provide a certain template for different questions, so that both parties can communicate better

On the left side, you can submit several related blog materials, similar questions, and encyclopedia links to Sifu. Examples are in Sifu in product comparison.

bug

After revising my previous answer , why does the time change? I still hope it is the first time. Don't update it, otherwise the ranking will be reduced.

6. The questioner

Question Restriction : When answering questions recently, I found that a few users posted two identical questions, and they both passed the review. The problem of seeking source code for course design and writing assignments has not been removed.

Problem matching : When the user starts editing on the issue interface, the official can match some problems with high similarity and have been solved to see if the user's needs can be solved, so that there is no need to ask questions

Describe a problem : At present, the official provides two templates, I think they can be subdivided. The length of the question does not have to be limited to more than 10 Chinese characters. For those who seek source code, provide exam or homework answers, they should be limited.

Failure to adopt the problem : If the problem posted by the user has not been solved usefully, the deletion of the problem needs to provide a certain reason, and the official can send high-quality creations in related fields for verification.

7. Image to code

Look at the picture above with this function. After copying, the line numbers are also copied, English; and Chinese; mixed, typesetting is disordered, and there are no parentheses.

It is technically difficult to identify the picture code function, but I believe that CSDN can do it well. Or restrict the questioner to take pictures and upload the code pictures that are blurry and need the answerer to run and compile by themselves (just looking at the picture can't solve it)

8. Remote control

Users in the CSDN station want to launch a remote control function

8. User interview

Many students around me are also using the CSDN app. I asked about the question-and-answer function module in it. Some of them have been used well for a long time. :

After asking a common question, the time to answer is too slow. Only the question of paying will be solved quickly. It is better to Baidu or ask others.

Too little money, too little event prizes

The same problem-solving idea, I am better than him, but did not adopt mine

A question only needs one acceptance, it can't hurt

Most users do not accept the correct answer, and some do not accept more than a dozen answers

Nine, CSDN recommendations

CSDN is promoting its own VIP all the time (the fees are very expensive), and the VIP is too separated from ordinary users. The functions of CSDN are very comprehensive, many and complicated, but each function feels a little bit worse, and it does not reach the top in China.

If the Q&A area only relies on incentives and cash rewards for users to be active, this function will fail. In particular, CSDN took the lead in developing a question and answer VIP. If you want to increase the stickiness with users, you can learn from other platforms.

Send out several events, such as the Spring Festival, Valentine's Day, Lantern Festival, National Day... You can set up several event essays to write interesting technical articles or small games.

Just like my evaluation articles for the skill tree and Q&A function this time, only the official staff will read it when the event is over. The operators of the articles submitted below should interact and give feedback in a timely manner. The official takes the lead in creating a good comment area. Otherwise what is the feedback.

Officials should set up more CSDN operating accounts, audit accounts, regional managers, etc., to be active with users on the site, or give some blog experts the rights and interests of community co-builders, and recommend high-quality articles to the homepage

In short, as the big brother of the Chinese community, I hope CSDN will get better and better!!!

In order to increase the publicity of CSDN, publicity articles have been uploaded on personal social writing platforms such as Zhihu , Blog Park , and Jianshu .
