I know your question was rhetorical but I'll answer it.
Its actually terrible to read on a wide monitor. If you were to give the content a max-width with some gutters its easier for your eyes to follow the lines. I always start reading a line that I just read! I'm talking about adding less than 10 lines of CSS, nothin major.
That's easier to fix. Just resize your window. Heck, if you use Firefox you can just press ctrl+alt+m for a mobile-like view without resizing the window.
