I've gotten used to the full screen (or width) windows. Mostly it's because of certain work web UIs that need as much width as possible. I agree with your statement that wide text is difficult to read. In Emacs I use Olivetti mode to narrow my text windows, I should probably do something similar for hackernews or other sites that would benefit from narrower windows. In Firefox, there's reader mode too, which makes things much easier to see.
