Looks to be an attempt at setting a readable line-length. http://baymard.com/blog/line-length-readability http://baymard.com/blog/line-length-readability I usually like reading articles with this width, but there's usually a different color background to differentiate the article from the page so there's not this huge white-space void. Other than that I thought the article easy to read.
