I think Heyuri had struck gold with the set up where every corner of the site was completely different. Porn can be found everywhere on the internet so there's really no special value to having an in-house section for it, while /a/ is very close to being redundant despite being active considering that a lot of threads on /b/ already have an otaku flavour to them

As it pertains to the textless threads, of course there's nothing wrong with them per se but there have definitely been an uptick. I'd even go as far as saying that it almost feels like a subtle spam effort. Probably just me being paranoid, regardless, at best it shows that a bunch of retards arrived on the site
