@Gargamel,
Quote:I used to google, in quotes, sentences I found too elegant.
I've used that method frequently, especially with the religious wackos. When someone comes here with one of those opaque, goofy religious rants, it is often possible to find the source which the author forgot to attribute. But i've also found it useful in other cases--sometimes people answer a question here by cutting and pasting directly from Wikipedia, or Answers-dot-com, or About-dot-com; and, as is so often the case, they forget to attribute their source.
Once, one of the religious nuts here who constantly argues against evolution put in a sneering post about a paeleo-anthropologist who had seen a finger bone and knew it belonged to a certain hominid species. He then waxed sarcastic about people who only see what they expect to see. He neglected to mention, however, that the author was a scientist, with 30 years experience in working with hominid remains. When i googled one line of his post verbatim, it returned two interesting results. One was the original article from which the quote was taken, and in which the quote wasn't chopped up the way this religious loony had presented it. That article, in full, told of the author's credentials, and crucially, pointed out that the site had been worked for three years, so the stratigraphy had already been done, allowing them to date any find they made with a good degree of certainty. The other interesting find was the quotes he used, chopped up the way he used them, at a creationist web site, which was probably the source for his sneer.
Verbatim searches are fun that way.
