Which came first? 4chan or the web? 4chan is place where insanity comes from. 4channers, the natives, pass insanity like bad gas. The river that is the internet flows from 4chan itself, setting internet trends, and even real ones.
Mark these words: 4chan is alive. Shoop da whoop.
A long time ago, in a place far, far away, the world gave birth to the internet. In this most holy alternate world, 4chan was born and so came the long-awaited destruction and slander of the human mind. And all was good.

What the Patriots are trying to protect us from.
But in 4chan, trivial information is accumulating every second, preserved in all its triteness. Never fading, always accessible. Rumors about petty issues, misinterpretations, slander... All this junk data preserved in an unfiltered state, growing at an alarming rate. It will only slow down social progress, reduce the rate of evolution.

Where Chuck Norris forsook his wisdom. Where Monty Python denied their genius. Where the ancient Flame Warriors sealed the great evil Stupidity. This monster eventually escaped by its soul resides there still. It is a testament to the eventual downfall of Mankind. Only when the almighty Banstick awakens (And maybe if Microsoft takes over the internet) will it be slain. Should Rosie O' Donald ever be allowed to merge with 4chan, not even Chuck Norris can bring her down on his own.
Hell would have made 4chan a business if Rosie O' Donnell wasnt trying to claim the Twinky of Delicious Hate.

A place where it simulates a bandwidth rollercoaster ride by screwing itself over with large quantities of anime images and data filled with anime japanese enthusiasts who are mostly japanese wannabes in a community who ripped its idea from 2chan.
"Damn, 4chan is down again and I wanna leech my daily dose of anime pictures and read what post flaming those elitists have done this time."

Fark + anime = 4chan.
4chan is as funny and interesting as you'd expect a board full of anime porn would be.
