/b/ is dead.
Shitposting now goes in /bant/ and /s4s/.
Porn now goes in /gif/, /h/, /d/, /s/ and /hm/.
Autistic meltdowns are now mainly contained in /pol/ and /r9k/.
The only thing /b/ is good for nowadays is that it's the only board that allows lolicon, and even then it'd be so easy to make /d/ the loli board and then delete /b/ altogether.
