Here are some inspo sites for long form articles with a focus on typography/readability (ignore the content/politics of the articles linked, they were chosen to illustrate the site design itself):

The Correspondent

The New Republic

Long Reads

I really love Anton Sten's blog design (changes often).

Tania Rascia's blog is a minimalist dream and almost feels like a git interface.

Kilian Valkhof's blog is unique/readable/attractive, though not brutalism by any means.

Dan Eden's blog changes often and is always well designed.

There's also the general style/strategy that was referred to as "snowfall" several years back. It was in reference to a NYT article that popularized the techniques and ideas , but by no means invented them. This isn't brutalism at all, but is very tied into the idea of "long form" editorial design.

I've really been into inputmag.com, reallifemag.com, theoutline.com for column articles, and almost anything from pudding.cool for features

The Atlantic did a recent redesign, and it looks great, but a bit more traditional.

Real Life is great and kind of more "brutalist" (whatever that means on the web).

Cargo and Readymag also have some great examples on their sites.

Also, we art direct all of our long-form pieces on Coax.

Hi Andrei - brutalism doesn't come to mind with these but I've been curating this style I categorize as "long-form journalism" pages: https://onepagelove.com/inspiration/long-form-journalism - I think there might be a reference or two in here for you

I also like the design of the blog you referenced. I read the article about the Impostor Syndrom. Very interesting. It's a notion that I discovered recently, and yes, the healthy self-doubt idea puts things into a different perspective.

Can't think of any off the top of my mind right now but this definitely sounds interesting. Keep us updated how it goes!
