I've experimented with this style on Wikipedia, with separate columns under each headline. It usually works well.
Newspapers don't have scrollbars. So they use columns.
This may be why phone-apps are so popular, their content is designed to be viewed only through the app.
CSS columns is cool, I didn't know about it. But not sure where I would use it either.
I really love multi-column, and appreciate horizontal scrolling. I've got an ultrawide screen, and I love that my site is one of the very few that makes an interesting use of a screen that wide. (There are articles on my blog you can easily read with no scrolling at all.)
I've gotten so many complaints over the years about my use of multi-column, including here on HN. It seems a very polarizing thing, even as I wish it were more common. The one time one of my posts trended it got a lot of hate about my blog CSS. That was a revision ago, though. I've made a bunch of adjustments to it since then, because I did read all of them, and tried to find some tweaks (including a few bits of JS) to smooth the experience a bit.
(Some group or groups at Microsoft during Windows 8 development must have passionately loved multi-column text and proper "newspaper inspired" typography and wanted to see it succeed, and they did not seem to survive the backlash against Windows 8, sadly.)
As one example, the "Golf with your Friends" subreddit always throws me for a loop due to its use of columns. I have no idea how to read it!
