Re: Frightening...
Googles search results algorithm seems to be based more on the popularity of results, not the relevance. I'd expect typing Squid on it's own should be more relevant to the mollusc, but that's not currently the case because result popularity has a higher weighting.
I see similar on the BBC news site. Sometimes a popular story links to to "You may also like" and sometimes a lot of people click that and a story from some years ago ends up in the Top 10 Stories side bar.
