Information collected by Google

I see from the Google Friends newsletter there is a video on Youtube which explains what kinds of information Google collects when you search it e.g. cookies. It is straightforward, with a female talking head and some writing on a flip chart, but nicely done and could provide a starting point for discussion on data privacy. Some of the comments are also thought-provoking (I wasn't thinking of the "She's hot!" comment, but I suppose that indicates that the video will appeal to a wide audience ;-)
