I had a Pinterest account back when there were genuinely great resource for niche things like Japanese graphic design.
Since then, I've moved to simply having a local image/video database UI app like Eagle[0] and checking Are.na[1] for interesting collections.
Thanks these are genuinely helpful. I also use/d Pinterest for this kind of use case and haven't managed to find many good alternatives
I've entirely replaced Pinterest with tumblr for that kind of stuff. It comes with the added bonus of having a community of other queer weirdos like myself
