I disagree. Just focus on making the forum good and making content.
People are asking for apps, dark mode, etc... none of that is important. You want a nice clean forum to interact with others on and share info. If you do that well, that's all that matters. Youtube took like 10 years to come out with dark mode, Mac also took 10 years... you want dark mode in the first week of this websites existence?
At the same time you must encourage discussion. The reason the left is are so terrible is the silence opposing opinions. Censorship sucks an open discussion is won by those who are intelligent.
