Ok so I had a bad experience on /co/ and I need to rant for a bit.
What made /co/ great were the inappropriate explosions of creativity that followed every new phenomenal cartoon and the adult discussion that followed. Back then, you could make a thread about a new show about a girl and her horse and people would come in to shoot the shit about it because they knew it was only a matter of time before a drawfag posted a picture of the girl sucking off that horse. Even the people who weren’t into that stuff waited for it because they could say "this fucking board, those sick bastards" while shaking their head with a smile afterwards.
The new fucking moralmods went out of their way to sanitize /co/ and turn it into just another cartoon forum. They killed the spirit and wild outlaw character of 4chan on that board. Not only did they exile adult cartoon threads to /aco/ and /trash/, but they followed them there to continue to police them.
One more thing, generals originally were made as a way to contain discussion when shows weren't airing, so that the catalog wasn't filled with 1-5 reply threads for a show that had been discussed to death. When a show was airing you were allowed to just make new threads regarding whatever topic you wanted, so long as it wasn't obviously an active attempt at spam. Now, for whatever reason, /co/ does the exact opposite, stifling discussion and making new popular shows feel unwelcome. Many of those shows end up having to take their threads to /trash/. I miss the chaotic topic spam when a really popular show was airing, it was fun.
