I held off on replying to this anon. I am really torn on doing this, however, I have as of late been thinking about enabling this feature (it is built into the engine and could easily be rolled out).
Philosophically I didn't like some of the decisions that 8chan used (I used it primarily between 2015-2016) and haven't used it since really. Board creation I felt split a great deal of communities, if someone doesn't like /pol/ they make their own, rinse and repeat, and suddenly you have 4-5 different /pol/ boards. This happened for many different communities on 8chan.
I like the idea of board creation, however, I don't want it to split communities that should just exist on one board. I think I will do some sort of community event in the near future and we can discuss if the majority of people want it enabled, the benefits/the downsides.
