A few years after graduation, including me, the students around me laughed and said that they had returned their knowledge to the teacher, chemistry, history, physics, Chinese, 45 minutes a lesson, over and over again, and there was not much knowledge that would really be used frequently after the college entrance examination.
But when I encountered the exam question again, the memory came back like a tide, choose B.
At the beginning, I could not have imagined that the knowledge of hard work would be used in the challenge test questions of hardcore members of station B, and perhaps accidentality was the most wonderful place in life.
In order to make you play more cool, Station B has added a "threshold for use"
In the eyes of some B station users, the answering system can be described as a totem-like existence, it is a guarantee of the same good, but also the materialization of the community atmosphere, the community and users can use this to determine whether the answerer is a deep two-dimensional enthusiast.
The answer system even once became a protective shield for community culture, before the B station because of the ghost animal ridicule star Cai Xukun, which triggered a fight between some fans and B station users, but this time the fan control comment failed to reproduce in the B station, in the eyes of the old users, this is to a large extent the answer system has played a role.
When the fan base poured in, but was excluded by a variety of problems, even through Baidu search to answer the question, it takes a lot of time, the new account application speed is not so fast, to form a fast, large-scale control review or brush praise is not easy.
However, with the expansion, the difficulty of answering questions has plummeted, and the conflict between user scale and community atmosphere has become one of the biggest controversies of Station B.
Recently, Station B has restarted the answer system, but the threshold is higher, the new feature is called "hardcore membership", only open to Level 6 B users, people can click on the homepage to participate in the trial, multiple areas to choose, 120 minutes 100 questions, 60 points passed.
▲ The hardcore member question bank is of good quality
Through the answer test, you can get the corresponding identity identification, while the number of special attention and blocking users have been improved, the most important thing is the "hardcore member bullet screen beta" function experience qualification, after opening, you can give priority to the display of hardcore member bullet screen.
This is obviously a change made by Station B in order to reconcile the contradictions between new and old users and maintain the community atmosphere.
The most basic level 6 threshold also means that about 4 to 5 years of B station use time, the quality of hardcore members' test questions is quite high, and users who pass can continue to write questions, and further enrich the question bank after passing the review to ensure the quality of the question bank.

This ensures to some extent that hardcore members are mostly fans, and there is less controversy about content or topics.
The answer system screens users, and the hardcore member barrage screens the bullet screen content, and the two-pronged approach can also protect the UP master and his expression.
Previously, chen Rui, CEO of Station B, also expressed the view that content-centric can balance the community atmosphere and user scale.
After the number of users of social products has increased significantly, a large number of new users with different preferences and different pursuits have entered, often forming conflicts with community culture, and the discussion atmosphere has become worse, expression has been misunderstood, and conflicts between users have become more and more intense, which is still one of the most controversial issues in Station B.
Differentiating users and content through design sills is one of the ways to adjust the atmosphere of discussion and community, and in recent years, popular social apps have provided corresponding features when they launch membership services immediately.
▲ Instant membership service
After remaking an Instant Member, people can filter the comments and choose to focus only on participating comments or only for members to participate in comments, and the immediate official describes this feature in the push:
Set dynamic comment permissions, only allow trusted instant friends to comment, sharing does not mean that you always have to be misunderstood and offended.
Even more than social applications, threshold design also has a good role in game products, maintaining fairness, improving the game communication experience, and even commercializing threshold design.
The threshold can improve the game experience and is also a "cash cow"
Thresholds have become the norm in game design, especially in competitive games with social nature, after a large number of players enter the game, the player's understanding of the game is different, the game level is different, this situation needs to be layered through the threshold to ensure the player's experience.
Whether it is a free-to-play game or a paid game, the game atmosphere is one of the important influencing factors for its long-term operation.
▲ Dota
Dota has a lot of experience in designing thresholds, such as the Warrior League mechanic, where players need to spend real money on "league tickets" to compete.
In this way, even if Dota is a free-to-play game, the threshold for payment will allow most players to correct their game attitude and reduce hang-ups and player conflicts. At the same time, the ticket fee can also be used as an event bonus and operating funds to promote the sustainable development of the game.
Nowadays, Dota has also derived the corresponding paid subscription service Dota Plus, providing data services such as record query, data comparison, ladder score, etc., as well as corresponding league tickets.

Latecomers "League of Legends" have more influence, more players, and are also more deeply affected by the game atmosphere, players quarrel and insults, hang up the game, actors and other issues have been complained about by players.
Therefore, the tournament mechanism of "League of Legends" is more complex, the threshold is more, in addition to the common ranking segmented competitive events, there is also a canyon top zone for high-level players.

Each season has a corresponding settlement reward, competing with people of the same level, and the dan position serves as an intuitive threshold to attract players to continue to work hard for this, and to a certain extent alleviate the problem of players fighting at different game levels.
Fortnite is one of the most successful games to commercialize the threshold mechanism, and the season communication card as a threshold in this game becomes a compound of game content and character skins.
Each season, Fortnite introduces new Season Challenges and items such as character skins, and players who don't pay can only get some of them by completing various challenges continuously, while paying players can directly purchase Season Battle Passes.
In Fortnite, the threshold became a purely commercial design, and on the first day of the third season in February 2018, Epic sold more than 5 million battle passes and earned more than $50 million in a single day, according to Gamesindustry.
This design was later widely used in other games, including Call of Duty and PUBG.
Thresholds are both a weapon for balancing the culture and atmosphere of the community and a cash cow.
One way to move forward
Whether it is a game or a community, with social attributes, they need to face a problem after they develop and grow, a large number of users with different preferences, different pursuits, and different entry times are in a product community, how to balance users and the original community culture, reduce conflict.

The introduction of "threshold" diversion users is one of the solutions, the B station hard-core member answer system, "League of Legends" complex and diverse hierarchical ranking competition system are the same, the user and content are layered, so that people have a good experience.
Of course, this does not mean that everything is fine to increase the threshold, there are many ways to cross the threshold, and people will not necessarily cross it in a unified way.
Take the hard-core member answer system of Station B, although the difficulty of the test questions at this stage is quite high, which tests the comprehensiveness of human knowledge, but this is not difficult to solve with the support of search engines such as "Baidu".
▲ E-commerce platforms can not only help you answer questions, but also open "creative incentives"
In addition, when the threshold of the early B station answer system was quite high, there was actually a corresponding answer package service on the e-commerce platform, and it was possible to pass the answer test with money, or that sentence - there will be a service if there is a demand.
And "League of Legends" has not been able to rely on a rich and diverse competitive threshold, completely solve the problem of hanging up, insults and other issues, especially the actor to control the game win or lose, involving money, competitive games will also be the same as "fake game", hard to fight can be eased, but it is difficult to completely solve.
More importantly, whether the threshold design itself can adapt to the community, which caused controversy when the member service was first launched, and the "member-only comment" function did give the speakers greater freedom and choice as a tool, but whether using paid membership as a threshold violated the original intention of a community to open communication.
▲Instant member function "Only members can comment"
The "threshold" design does not solve the conflict once and for all, it is just a step in the spiral of a product.
The hard-core member answer system cannot completely solve the conflict caused by the community culture of Station B and the large-scale growth of users, which is only a small step forward for Station B.
After many years, the re-entry of the "hardcore answering question" system at least re-gave the old users of Station B a chance to meet with their friends again.
