Looking at his format, I can't help but think what could have been if he had only used org-mode instead!

iD software would never have become anything of note, of course. Obsessing over his emacs config, but missing C, and so becoming the master of the C core. We would probably never have heard of anything like "long lines mode".

Growing up with the iD games, I am not so sure what I would prefer anymore. Actually I think I would have preferred the latter. Which is almost sad. A wild testament to emacs, to be sure.
