I too spent some time on ClickClickClick and I must admit that the experience was quite sobering.  There is nothing unexpected in the experience for anyone familiar with the intrusive nature of web data mining, but it is none the less scary to see it presented in such an interactive and violating form.  This will certainly be a teaching tool that I will turn to in the future for some of my end user education platforms.
