https://www.are.na is kinda like this in a wierd, niche tool for internet/image archiving. You either love the interface or don't get it, but a potential replacement nonetheless.

I showed my friend are.na (after deciding I liked the concept) and they called it "a masculine-branded pintrest clone". I had trouble disagreeing, but I'm open to being convinced otherwise.

I especially love the shots of seemingly boring city architecture like this: http://ffffound.com/image/913174394559f0f170e9af85417302ce83...

I didn't know I want this site until now, I suppose this kind of stuff is on artsy Tumblr blogs but I don't know where to find those.

I don't know about "seemingly boring", that's a pretty famous building in Shinjuku.

It's in the post-war Metabolist style. If you want more of that stuff specifically, go where architecture students hang out. Ideally IRL...

There's also (again, specific to that style) a good recent book of interviews on Metabolism by Rem Koolhaas et al.

If you want brutalist architecture, @brutgroup on IG is pretty good: https://www.instagram.com/brutgroup/

Thank you for the link - exactly what I was searching !

Very nice, thanks.

Pintrest comes to mind as the most well-known Ffffound copycat, but the interface isn't as clean and they gate their site.
