I don't think these are reasonable critiques of OP. 7chan, while more active than a site like sekai yon chan is absolutely "dead". What OP identified, I believe, could be better stated as complexity and engagement. It is not entirely requisite that an insular group of posters exist, but it is necessary that their exists some sort of mutual understanding. In a space where everyone is coming and going and there's nothing guiding the discussion the discourse never progresses beyond shallow formalities.

A community, I propose, is dead when new users cannot be added or make substantive contributions.
