I would have appreciated a sensible max-width on my fullscreen desktop browser.
It's frustrating when someone decides "damn the system" in the name of a proto pre-design-standards aesthetic instead of just making sure standard zooms leave their content at 12-14 words per line.
edit: I could have used curl, an html processor and a pager like less or more
This is mostly the websites fault, of course. It's the same forced-layout mentality that has always caused problems on the web.
I have a pair of 27" monitors and almost never maximise windows - the exception is when working with very large images that need the full resolution.
I disagree that a sensible max-width is wasted screen real-estate. Even after resizing my browser I'd prefer my content to have a little bit of space to breathe.
