Lmao
I dont even get what /b/ is? A bunch of nerds who watch anime, make memes and spam/hack shit?
No it's 4chan's "open forum" there are other categories for the specific type of stuff, some of that included. They have music, movies/tv, hot bitches, gifs... all kinds of things. Are there a lot of nerds on 4chan? Sure. Are there a lot of nerds on here? Sure. Also just a bunch of normal people who fuck around on the internet just like anywhere else though.
BUT... also a lot of weirdos that make anything that happens on here look very minor in comparison but like I said almost all of that is in /b/. I haven't lurked /b/ in quite some time but I've heard it's a lot more regulated and tame now than it used to be.
That said if I decided to again I would browse /b/ by proxy just like I always did lol.
