/g/ isn't insane, you're taking everything that people say on 4chan seriously. Which is a mistake.
Huh? No.
And I say this as a regular visitor of /x/. The mods seem downright useless some days.
/x/ is the only board that actually does get raided. it's probably the worst board on 4chan (i'm a pixie AMA).
There is some genuinely interesting stuff on /x/ once you filter out the fakers and the roleplayers.
I realize mods on 4chan is a touchy subject, but /x/ could use a good mod that deleted excessively repetitive threads. there are some boards where that's not such a big deal, and some boards that thrive on repetitive and troll threads (I'm thinking of 4chan's pressure release valve, /pol/). But /x/ would be better served by having a mod conscientious of, not so much curating good content or killing trolls, but deleting the EXTREMELY repetitive threads that inevitably go nowhere.
Also, it is a matter of opinion if the roleplayers are a problem. I would argue that the lazy, bad roleplayers are the problem. I think they add color when they're good. Part of the excitement of /x/ is that it exists on the fuzzy periphery between fact and fiction.
i do like x's archived threads, where people dump youtube videos and wiki links
Also, some of the boards are full of people who can be described as insane- despite not having porn/gore/etc. For example, /g/. I don't agree that it's inaccurate to say 4chan is vile in general, and I certainly agree with the sentiment that 4chan is the best and worst of the internet- or at least the social part of the internet.
