I’m a nerd who’s done some typography, and I hate monospace. The distinctive thing here is that nerds are about language, and the good linguistic interfaces to the machine are mainly monospaced just by historical accident. It’s not like we’d invent it over again if we hadn’t thought of it until now.

Now that it’s established, of course, we’re all pretty much locked in. Most of the text on my screen right now is monospaced. I mean, good luck writing code in a proportional font: pretty much every language and text editor assumes you can align with spaces, tiny punctuation looks huge, etc.

But saying that monospace is inherently nerdy is like saying that, say, slashes are inherently path separators.
