Lines of > 80 characters are really the last jabs at the dying corpses of typography and taste in the digital world. Typographically proper paragraphs are not wide across, because that forces the eye to move more while reading. This is a basic fact that has been known for literally longer than we've had printing presses.

Wide lines are barbaric, and I'd go so far as to say that languages that can't be rendered comfortably in 80 character lines are nothing more the primitive tools of barbarians.
