Comments on the internet are a false reality.
That's why people are drawn to them.
No power? You can be a hero in this new world.
Even if it's all bits on a screen.
Because people act based on those bits, just like they act based on stories in newspapers or word of mouth.
It gives power to the powerless.
In theory, a good thing; except that history teaches us how the powerless are unable to assume the responsibilities of power, and so the most promising revolutions turn into the Guillotine Terror, shooting the Romanov children, Pol Pot, etc.
