I collect old newspapers and back then info density was way higher (for an _amazing_ coffee table book, google "nytimes complete front pages"). So much critical info above the fold.
I think high information density === high intelligence. Getting sort priorities right is very valuable and important.
The past few years the web seemed to be going the other way. Good to see people still rowing in the other direction.
Other examples:
I designed my blog to allow one to zoom in/zoom out to see ~20 years of posts at once (https://breckyunits.com/).
I've got some stuff coming out to promote (and make it easier to build) highly information dense cheat sheets (I'm trying to get the name "Leet Sheet" to catch on - https://pldb.io/blog/leetSheets.html)
