I argue with our designer about text justification at least once a week. I want almost everything justified, Paul approaches things case-by-case (as if specific circumstances have specific needs, pffft). I like paragraphs to look like finely marbled rectangular blocks, he wants words to be readable first and foremost (the weirdo).
Little did we know there was a solution we could both agree on, thanks to the website XKCD. Thanks, XKCD!
