imo, if I have an Apple monitor used by a large number of potential site visitors set at maximum resolution, then the page should at least center the div if you are going to do a fixed width layout, so 1/2 of the right side of the screen isn't a plain otherwise empty blue background. That way at least only 1/4 of the page is empty on both sides, which is less distracting.

Fluid width with adjusting fluid left/right % columns (divs, or table if you must) also works.

If you choose to make your browser window wider than a line of text you'd comfortably read, you also can choose to apply any settings that will make sites look more to your liking.

It bothers you so that you won't even read the blog post, swoon!
