Great search engine safe for children if filters are on strict and no chance of virus infection unless you go to a site that has viruses and all that on ITS NOT GOOGLES FAULT ITS A SEARCH ENGINE!!! and about the cookies go look up about them they take no personal info just settings and other stuff perfectly safe and if you don't want them turn off cookies easy as pie!
The best search engine there is, I love how you can easily use the map off of Google to fine where people live for local pick up off of eBay and when I'm lookin for images not websites Google makes that easy to AND THAT MAKES GOOGLE SO COOL.
Google tracks all your movements, when you login into sites, most of them use scripts off google that track everytime you load the page, login, most the sites you visit, when you search something sometimes the site puts a cookie on your computer without even visiting the website, just by looking it up on google. If you don't believe me, clear all your cookies, goto tools and have it prompt you on all the cookies and you'll see.
