Researchers at TU Graz have issued a report on the power of Google, which I have not seen mentioned here; ignore this message if it already had been discussed.
This report investigates the power that Google has over current information reception today. We all know that what does not exist in Google is hardly visible to the world; and obviously, the ordering of search results has a big influence on what kind of information the interested searcher gets to see.
Of particular interest to the readers of this board may be the section, "Empirical Evidence of the Google-Wikipedia Connection", investigating the position of Wikipedia entries in search results on Google and other search engines.
QUOTE
Since most material that is written today is based on Google and Wikipedia, if those two do
not reflect reality, the picture we are getting through “googeling reality†as Stephan Weber
calls it, is not reality, but the Google-Wikipedia version of reality. There are strong indications
that Google and Wikipedia cooperate: some sample statistics show that random selected
entries in Wikipedia are consistently rated higher in Google than in other search engines.
...
The other conclusion is scary: Google does in a strange and unknown way privilege Wikipedia entries –
followed by Yahoo; and Google does this intentionally more with the German version.
