Yeah. I visit everyday like back in 2012 when this was super active. Although it's sad that the discussion is practically dead in most boards, I'm glad for the chill ambient and appreciate how the little activity we have is actually fairly interesting.
I don't participate as much as I used to, mostly since now that I'm in college it sucks most of my time, although I'm active in our /og/ boards.
i miss it bros..
Why are these boards active but the main ones aren't?
Because they have threads that interests people?
If by "main" you mean yume nikki related boards, that's simply because there's absolutely nothing that could be said about yume nikki that wasn't already said in the past 11 years this imagebaord has bee online.
Idling slowly is preferred here.
