I have the opposite preference -- I prefer full-width text so I can have two pages up side by side on a 16:9 monitor, and usually 3 up on a wider format. I feel like I'm constantly grumbling about all the wasted white space on pages and their general total failure to be responsive to a half width screen that _isn't_ a mobile phone/tablet. Maybe we should just have an open standard for default display settings so we can both (all) have our cake?
