All /x/ is anymore is zoomers doing gay creative writing exercises trying to be the next backrooms. These can only be kids who were raised on Five Nights at Freddy's fanfiction.
4chan's userbase in general seems to be skewing younger than it ever has, currently. It's true of every board. I assume it's a combination of older users heading to Twitter or just aging out of using the Internet, while kids flood in from TikTok and YouTube videos about 'da scary dark web where cool stuff happens'
This wouldn't necessarily be bad for the site, except that zoomers are the brownest generation yet, so by consequence the userbase is also extremely brown.
You can open any board about entertainment and basically whichever thing is most appealing to (brown) children, within the subject matter of that board, is what has the most discussion
/v/ & /vg/:
>undertale, phone games, off-topic threads about digital circus / gameoverse / etc, complaints about not being able to afford a PC
/a/:
>one piece, jujutsu kaisen, chainsaw man, dandadan (if you're unfamiliar with anime: all zoomery Netflix shounen anime)
/mu/:
>literally just Kpop (zoomers' favorite thing)
etc.
It's also visible in the overall culture of the website, which has skewed super left wing in a distinctly "autistic teenager" sort of way. You can open any thread on 4chan today and find kids having meltdowns about how AI is depleting the Earth's water supply, random posts relating orange man or capitalism to the topic at hand, etc. Gives you a window into how unhealthily politically obsessed the average child is in 2026 actually
