Nice. There's no map entry for this one and it's not linked from anywhere obvious - you got here by clicking the logo five times fast, or by reading the page source, or by guessing the URL out of pure curiosity. All three are exactly the kind of behavior this site was built to reward.
[WRITE ABOUT THIS: put something genuinely just-for-you here - an inside joke, a real secret, a tiny game, an ASCII drawing, a confession about your actual favorite text editor. This page exists purely because you thought a secret page was cool, which is the entire philosophy of this website in miniature.]
(there are a couple more of these scattered around. good luck.)
