Jwz knew that, because he worked on Lucid Emacs.

Wow! Source?

This is known as Zawinski's Law[1]:

Uhhh. jwz.org checks the referer header for hacker news and redircts to a picture of some male gentailia in a egg cup, with some text of what jwz thinks of this site.

I'd advise linking to a archive.org version of the url.

Uhhhhhhhhhhhhhhh, alrighty then........ can't edit or even delete now. Thanks for the heads-up....

(Mods, could you change it if you see this?!)
