While 80 characters may be a bit restrictive, there is a need for a hard limit of something.

I've found that in the absence of a hard limit, you all too quickly end up with a codebase riddled with 250+ line monsters forcing you to scroll right and left all over the place just to get the faintest smidgen of an idea of what's going on. It's a maintenance nightmare.

Meanwhile, GitHub won't show lines longer than 132 characters (on Windows) or 123 characters (on the Mac) without scrolling, no matter how wide your screen.

I personally find 100 seems to strike the right balance.
