This article is terribly difficult to follow the flow of text. I've never understood the desire of some designers for columns of text on the web. Web pages are infinitely tall. Why would you want to replicate a restriction of old media on a new one? This implementation is proof that it's not a usability win.
I don't follow how columns is a restriction based on how tall a text is.
Columns are neat because they limit the width of the text, which is easier to read since you don't have to move your eyes as much for each row. It also helps compact the text somewhat (that of course isn't as much of an issue on a web page, but readability is still important).
Since the page in question have relatively short paragraphs splitting them up two columns is quite nice in my eyes. Imagine if there were no columns, that'd mean that the paragraphs was about twice as wide as tall - not that pleasant to read and it wouldn't look as nice. A lot of pages have columns (for menus etc.) on the left and/or right so they have a natural limit on the width for the main text (which is good), this site doesn't and is why the columns are preferable (IMO). If the window is very narrow the site falls back to one column, neat.
Renders fine for me in Windows on Chrome and Firefox but if there are issues for others that's of course bad and can be quite frustrating.
