Wow!I found this article and I was shocked reading it,although I knew all these!You will see that Google knows almost everything about you,including your name and address!And here is what would happen if Google was evil!Oh man,I think I'm going to uninstall all toolbars,accelerators etc!
It's so scary,don't you think?We give them the right to them to have all that information about us and we don't even care or ask questions!
