While it did away with the horrible 2-column layout, it looks like the article was writen with those columns in mind, so it uses short paragraphs that look good on 2-column, but feel a bit weird on a wall of text.
My (barely existant) OCD is going haywire over this article as I read it...
OT: Anyone know why all browser vendors implemented this CSS columns aberration so hurridly..? I have never seen a good use for them, so painful to read. It's always some designer trying to show off their "epic" CSS skillz.
