4chan has been around longer than Facebook, and is on a distributed back-end (globally). It was the first test of a distributed anonymous network. Like Bitcoin, it was NEVER meant to be as big as it is.
It has a HUGE cultural impact. Dogecoin was born there.
It's purpose is to create "Mind Viruses" (Which is what "meme" ACTUALLY means) these days. Who knows what it will be used for next.
There's also (among the confusing stuff you won't get) a lot of really disturbing shit there. It's not for the squeemish.
