Ah, this thread. How I've missed you.
Here goes
Back in the day, /b/ used to be great. There was much more OC coming from anon and they actually did meaningful things. Then something happened, I don't really know what it was but all the older, more useful anons stopped showing up (I'd rather not post what they're called for fear of mod punishment). The OC started to disappear, and the threads started getting shittier. I was still on it trying my best to avoid the gore, CP, and threads of the like when I stumbled upon an gif of a person beating his German Shepard with a golf club. I decided that was the last time I would ever visit /b/ and that was it.
Nowadays, /b/ is a shadow of it's former "glory." I use that term loosely because there never really was a glorious period for /b/. I see them now as children using the mask of anonymity to say and do whatever they feel like, mostly being racist. They use this mask to say and do what they're to afraid to in real life and live vicariously through the 5 or 6 anons that actually succeed. Most of them are the type of immature people you saw beating "the cake is a lie!" into any and every person that so much as mentions the word cake.
My opinion of /b/? I don't see them as the asshole of the internet, I see them as the appendix. Something that was useful at one point or another, but somewhere along the line it became useless and is now just there.
