Maz's mention of ezresults misusing material form WP reminds me of a research problem I had this week -- which relates to another thread in this maillist.
I've been rewriting the article on king [[Hezekiah]] of the ancient kingdom of Judah (my work is up on the English Wikipedia, if you're curious), & encountered the problem that the material an anonymous contributor added that Hezekiah's reign could be dated by an eclipse conflicts with the dates of two widely-quoted scholars. So I thought to use Google to investigate just who "Professor Aurel Ponori-Thewrewk" was, & learn just what he said in the cited article, & how reliable of an authority he was.
The anon contributor only provided an incomplete citation for Ponori-Thewrewk's work, so I cut-n-pasted about ten words including his name into Google to see what I could find -- which was two different sites that were using Wikipedia material. Fortunately, both credited WP as the source, & had the proper licensing notice attached. (I couldn't find the reference page that lists known users of our material to see if they were listed. Thanks, Mav, for the link.)
As for Prof. Ponori-Thewrewk? Except for some pages in German & Hungarian (the German ones appeared to be either from a college catalog of classes or a reading list; I don't understand Hungarian at all), the only explanation for who he was came from another Wikipedia page -- [[eclipses]] -- which identified him as the former director of the Budapest Planetarium. I still have no idea what he actually asserted concerning the sundial mentioned in 2 Kings 20:8-11.
Just an example of why including proper citations ("X says Y") is important, not only for NPOV reasons. (To tie in still another thread.)
