I've been randomly looking through the referer log for the last day or so, and have found a few amusing things.
Here's a site that republishes some Wikipedia articles: http://din-timelines.com/cyclopedia/dir/index.shtml
This is rather tasteful compared with the Fact Factory; there are ad banners at the top and bottom, but not too obstrusive, and everything is explicitly credited and linked to Wikipedia -- there's even links to take you to the article at Wikipedia for view or edit. It's not a fork, just an encapsulation.
This Fox News column links our article on [[Geosynchronous orbit]]: http://foxnews.com/story/0,2933,62200,00.html
This Salon column links our article on [[Leet]]: http://www.salon.com/tech/feature/2002/08/28/0wnz0red/index.html
http://www.why-is-the-sky-blue.org/why-is-the-sky-blue.html links our [[Raleigh scattering]].
And of course in the middle east department, we have links to:
[[History of ancient Israel and Judah]] from http://www.palestinefacts.org/pf_early_palestine_israel_antiquity.php
[[Mohammed Atta]] from some site claiming 7 of the 9/11 hijackers are still alive: http://www.whatreallyhappened.com/stf3.html
