I don't know why, but I'll tell you this.
This site has nothing to offer anybody. There is no quality content here you cannot get more quickly and efficiently elsewhere. This is an addiction which reduces your productivity, attention span, and free time. You are becoming more bitter, narrow minded, haughty, and old. Leave now and block this site. There is nothing here but slow, lonely suicide.
People do not have arguments here. Posters do not engage one another on key points, they nitpick with greentext and mock each other. Nobody is interested in the truth; people are battling for fleeting moment of superiority. Active commenters are loud jackasses who stumble into one internet fight after theanother, anxiously keeping ten tabs open to ensure they keep the last word in all of them. An insightful post is one in ten thousand, and no matter how hard you filter this place you are still searching for diamonds in a garbage dump.
This place is not making you happy. You are not having fun. You are not gatherig stories to tell, learning, or growing as a person. instead you chuckle every thirty minutes and are occasionally spurred to masturbation by libidinal posts or pictures. You are addicted to readily available information and pressure free social interaction. This place is slowly poisoning you with misogyny, narcissism, a false dichotomy surrounding normalfags, and insecurity.
I'm not telling you to b urself. I'm not telling you to go outside. I'm not even telling you to make friends. just leave 8chan. Do anything else!
