Does the Internet help democracy?

A lot of people thought the internet would help democratize the world.
More people and groups would have access to information, and the ability to mobilize from the ground up would gradually undermine concentrations of power—that was the idea, at least.
But the reality has been quite different: Instead of democratizing the world, the internet has destabilized it, creating new cleavages and reinforcing the power structure at the same time.
