4chan is an imageboard. It is often considered the bottom of the internet, but it's really a matter of opinion. I've found some bad ass wallpapers there.
@ Luxorz- It's organized fine, AFAIK. Maybe just because it's unfamiliar to you?
4chan is where most of the internet memes you know, like Rickrolling and lolcats, came from. It has definitley got a reputation, though. And whatever you do, DO NOT EVER VISIT THE RANDOM SECTION, OFTEN KNOWN AS "/b/". WhAT HAS BEEN SEEN CANNOT BE UNSEEN.
All of the other are ok though, except for the weird "Alternative Hentai" section, which is full of horrible things...

"The "random" board, /b/, follows the design of Futaba Channel's Nijiura board. It is by far 4chan's most popular board.[22] Gawker.com's Nick Douglas summarizes /b/ as a board where "people try to shock, entertain, and coax free porn from each other".[3] Certain post numbers are sought after with a large amount of posting taking place to "GET" them. A "GET" occurs when a post's number ends in a special number, such as 12345678, 22222222, or every millionth post.[23] A sign of 4chan's scaling, according to moot, was when GETs lost meaning due to the high post rate resulting in a GET occurring every few weeks. moot estimated /b/'s post rate in July 2008 to be 150–200,000 posts per day.[24]
/b/ has a "no rules" policy, except for bans on certain illegal content, such as child pornography, invasions of other websites, and under-18 viewing, all of which are inherited from site-wide rules. The "no invasions" rule was added in late 2006, after /b/ users spent most of the summer "invading" Habbo Hotel. The "no rules" policy also applies to actions of administrator and moderator, which means that users may be banned at any time, for any reason, including no reason at all.[25] Due partially to its anonymous nature, board moderation is not always successful—indeed, the site's anti-child pornography rule is a subject of jokes on /b/.[13] moot told The New York Times, in a discussion on the moderation of /b/, that "the power lies in the community to dictate its own standards" and that site staff simply provided a framework.[26]
The humor of /b/'s many users, who refer to themselves as "/b/tards",[26][27] is often incomprehensible to newcomers and outsiders, and is characterized by intricate inside jokes and black comedy.[27] Users often refer to each other, and much of the outside world, as "fags".[13] They are often referred to by outsiders as trolls, who regularly act with the intention of accumulating "lulz"—a corruption of "LOL" used to denote laughter at another's expense.[26][28] Douglas said of the board, "reading /b/ will melt your brain", and cited Encyclopedia Dramatica's definition of /b/ as "the asshole of the Internet".[3]
Mattathias Schwartz of The New York Times likened /b/ to a "a high-school bathroom stall, or an obscene telephone party line",[26] while Baltimore City Paper wrote that "/b/ is the kid with a collection of butterfly knives and a locker full of porn ... in the high school of the Internet".[13] Wired describes /b/ as notorious.[27]"
The best advice I can give is to NEVER GO THERE. IT IS THE BOTTOM OF THE INTERNET.
