You've seen The Truman Show, right? Oh, no? Okay, go ahead and do that. It's cool. I'll wait.
Good movie, right? Now imagine if Truman had an earpiece, and into that earpiece is piped the reactions of every single audience member across the land. Now imagine that they are all shouting commands at him, and Truman must do the first one he hears after finishing a task, regardless of what it is.
Walk. Run. Dig. Rifle through your pockets. Switch directions. Break some shit. Fight that guy. Throw your wallet away. Jump off that cliff.
Something very much like that is happening right now on the Internet. It is a phenomenon called Twitch Plays Pokemon, and even if you are like me and care nothing at all about Pokemon, I urge you to keep up with it. It is endlessly fascinating.
