Google Search History

well i noticed this the other day....

i use firefox... and normally have many different tabs open at once... (like having many IE windows open)

if i am logged into gmail... and in a new tab or window... i open google... on the upper right i see search history... click on that and it asks you to login... i login... and it shows all my searches since oct 05... also under trends on the left... you can see when you search the most by time of day... day of week...etc...

interesting that google has my email and are also tracking my searches as well... are they getting to big for comfort? or just another arm of big brother?
