All boards on 4chan and world4ch are shit. /a/ is no exception.
The only reason I ever visit /a/ are the Lain and Taiga tripfags. It's like watching monkeys throw shit at each other, when suddenly one deformed monkey generates a turd so huge it's bigger than all the other monkeys combined, throws it on the other monkeys and all the other monkeys are like "what the fuck, where did you get a turd that big?" and then the deformed monkey throws another turd even larger, in fact so large that all the monkeys are swimming in shit, breathing it, transforming into it.
