book i did an experiment i wanted to buy as much as possible from amazon for one year and find out as much as i could about the company as part of this vast i wanted to know what information about me amazon was actually storing and not only when i bought product but also when i just looked at things without buy. the company took a long time to release the data which it's required to do under european law after some back and forth they finally sent her a cd. i found a lot on this cd the last 15000 clicks from the past year were on the rigs and if you were to print out my amazon data set on paper you get about 15000 pages of appeal. but she hadn't actually even bought that many things from amazon just looking at them was enough to. click there were 50 columns for every click
