Google Personalized Result

[Mike]

A few weeks back I showed a link about Google's personalized home page, a few days after that they introduced Google Search History. Using GSH, you can track how many searches you made a day, what they were, etc. Just today I was searching for something, and it showed a note about Personalized Search Help.

As a My Search History user, you've been storing a history of your searches and the search results you've clicked on. Personalized Search now uses that history and orders your search results based on what's most relevant to you. Early on, you may not notice a huge impact on your search results, but as you build up your search history, your personalized search results will continue to improve.

I searched for '> < +list', and it returned about 3 programming sites, and then something about the SAT's. When I search logged out, it returns 2 programming sites, the SAT site, then something about a Canadian moving company.

I think it's a great feature, but it's kind of scary. Since I am using all of Google's services (pretty much), Google now knows:
My email
What I've been searching
What I want to see when I'm searching
What groups I'm a part of
Where I'm going on vacation (via Google Maps)

...it's useful, but scary. *Puts on tinfoil hat*

EDIT: On a semi-related note, I just did my 1,000'th search =)
