The internet has made it easier to break reliance on the mainstream media, and look through the world with your own lense. In a sense this has made things worse, in that access to billions has paradoxically led to people hiding in their own echo-chambers. But overall I'd say that's a positive, in that it allows a variety of thoughts to spread, makes it harder to suppress news stories or groups, and makes it easier to expand anti-establishment movements such as my own (libertarianism).
If there is any hope to topple the two-party system, it is with the internet. Yet it might just take down everything else with it.
