Video in Class Today

My personal opinion on this video, I would have to say is quite scarey. When I get on the internet to search something, I'm hoping that what I search is private to me or to who I choose to share it with. Knowing that the internet will take my older searches & use them in Ad's on other web pages that I get on, just shows me the the web pays a little too close attention of what kind of things I like or what I search. Yes, it can be helpful but is it completely appropriate? It scares me to know also that other people can use my searches to find out what kind of person I am too. Not cool with me. I don't want complete strangers involved in my life...
