Cracked: It's amazing how much shit people will put up with, as long as you give it to them slowly. Like the way nobody notices gas prices going up, as long as it's done a nickel at a time.
But I can't think of a more dramatic example than the way spammers have ruined huge chunks of the Internet, and the way we kind of just let them. You can't get from Point A to Point B on the Web without swimming through a sludge of spyware, malware and viruses. It dictates our entire behavior online, and we've kind of just gotten used to it. I think this is amazing, considering that if even a tenth as much bullshit existed in real life, we'd be demanding military intervention.
