I'll be honest: I have no plans to actively promote or develop Nigrachan at this point. 47chan is basically what this place was intended to be, making it sort of redundant. On top of that, I don't really have the time or motivation to push things forward just for the sake of existing.
If things grow on their own, that's great. If nothing really changes, then that's ok too. In any case I will be leaving it open indefinitely, much as Pool's Closed is.
