"Many people with cognitive disabilities have a great deal of trouble with blocks of text that are justified (aligned to both the left and the right margins). The spaces between words create "rivers of white" running down the page, which can make the text difficult for some people to read. This failure describes situations where this confusing text layout occurs. The best way to avoid this problem is not to create text layout that is fully justified (aligned to both the left and the right margins)."
You shouldn't turn on justification without also turning on hyphenation.
If you add 'hyphens: auto' and '-moz-hyphens: auto' then it looks much better on Firefox. Chrome doesn't support hyphenation though...
Interesting, though the readability problem from the original text has much to do with trying to justify text in a very small column, which means excessive spacing has to be used.
It is presumably being down-voted because it is off-topic; This is not a post about web design.
Sure, CSS is on-topic on HN, just like this article about cryptography is on-topic. However, commenting on the HTTPS certificate particulars of a site with a blog post about CSS would be similarly off-topic in a discussion about that blog post :)
(Personally, I am on the fence about the appropriateness of the comment, but I hope I have shed some light on why others would down-vote it)
