Google cache (text only) content is: Knock, Knock. who's not not there? hakeem. From this, I doubt the site contains anything edifying or informative. Perhaps the submitter "haberdasher" should explain why he submitted this to HN, since the site is down and we cannot experience it for ourselves.
The site is mostly an experiment of sorts.
...and the server is back. Someone pasted in a user manual or some massive text.
