Deborama's WWW Number 2 - 6 degrees of Wikipedia

The second ever Deborama's WWW (Wednesday Website of the Week) is Six degrees of Wikipedia. In case the name is not self-explanatory enough, it works like this. You type the titles of two Wikipedia-articled people, places, things or concepts into the two search boxes provided and click on "go". It returns the number of links that separate them. I was astonished how short the links are. I tested it first with my ex-brother-in-law (the only near relative I was sure would be Wikiable) and HM the Queen (entered as Elizabeth II). There were only four degrees of separation; in fact, only three if I did not exclude day-and-date pages. (Try it and you will see why: Wikipedia cross-references all the dates it cites on grand index pages by year, month and day.)
Postscript: SInce just after I posted this, I have not been able to access this site; I keep getting a server-down message. Apologies to readers who tried it and couldn't access.
