by that I meant that Google modifies my search results based on my past searching history, and shows me the results it "thinks" I would be interested in.
For instance, if I've searched for "India Mobiles", "Indian Cricket", "Indian Politics", Google will try and show me pages with some Indian connection the next time I search for even "Politics".
This of course happens if you're looged into your Google account.
There has been a lot of controversy about this and this basically is a form of privacy invasion. I DON'T wan't my searches to be categorized. If I'm searching for granny fisting porn, I don't want anybody else to know about.
Its as if Google is "looking out" for me, something I don't like or appreciate.
