This rant feels a bit banal, like it's going up against a straw-man just to be ... a rant. On one hand, I can't think of the last time a developer in an org I've worked with hasn't <i>conspicuously and regularly</i> used text windows wider than 80 columns. On the other, well-written code (and prose!) also exploits <i>limiting</i> line length for clarity and readability. There's clearly a balance, helpful rules of thumb paired with useful times to break those rules.<p>To be honest, the worst regular example I encounter, in either direction, is Markdown source with no hard line breaks. Markdown fully supports them, and trying to read paragraphs in whatever-hundred character lines is a painful exercise. Such irony, since part of the beauty of Markdown is dual readability in both source and rendered forms.
