A post over at John's inluminent/weblog reminded me of a fun site I hadn't visited lately, the 404 Research Lab. When a web server receives a request for a page that does not exist, it returns an Error 404. The folks at the research lab have collected and categorized many of the best 404 errors on the net. Anyone fancy a quick game of Zork? My favorite is the sexy librarian at librarian.net.
