Encyclopedia Dramatica was KnowYourMeme but for teenage boys who think calling some one a fggt/goatse is the peak of comedy. The “offended” page was just a lot of shock imagery - gay porn, gore, vomit, shit (iirc it also played stuff at max volume). It’d be linked on articles that were less than nice.
Oh it's further than that. It's 4-chan users from /b/ who still think worshiping Hitler, calling black people the N word and going around spewing any racial slang around is still the coolest thing to do. ED isn't even an ecyclopedia, it's just the internet's big black book of people the internet doesn't like in the form of lolcows, controversial people who made themselves out to be shitty people. All of these things and more for people to learn about and get personal with since they're all openly doxxed.
