There's an episode of
The Twilight Zone ("The Monsters are due on Maple Street") in which aliens periodically turn the power on and off for only a few of the residents of a typical American neighborhood. The people, who have little information about what's going on and immediately have no explanation for what's happening, turn into a panicked mob as the accusations fly.
This board, sometimes,
is that neighborhood.
