Wait, why wouldn't the solution be "define a max width"? Site authors should not be wasting your window width, windows should not be "too wide" for text, and you shouldn't have to choose between the two solutions you mentioned.

Only because it seems to me that if the user really wants a terribly wide window … that's his choice. Who am I to prevent someone from doing something which seems stupid to me? Maybe he wants a half-inch high window at the bottom of his screen where he can scroll through my text slowly, or something. His call, not mine.
