>> 2ch is made popular for news4vip, 4chan by /b/
>> If 4-ch wants to be popular, dqn has to be popular first.
DQN and /b/ are very different boards. The atmosphere of both contrasts greatly, much past the fact that one is an fast-moving imageboard the other is a slower-moving textboard.
Racism, sexism, and blatant flaming may not get you banned on DQN, but it is looked down upon (most of the time) by the userbase. If 4-ch were to use a /b/-like board to gain popularity, do not expect DQN to be that board.
