thanks a lot man, this is really helpful: veyr understandable. (first time that I read in clear letter that this kind of technologiy is designed primarly to share information. And it is a shame that here in Europe laws don’t force corporation to build technology that has as a goal the privacy first. I am passionate in literature and Cultural studies, thus if we were living in another world I believe I would not read this stuff, because my heart beat for humanities (in a finite and short life: reading all Cormac McCarthy’s opus for a second time it would be for me highly preferrable than learn about networks, but this is the world I live in and I am tired of these damn corporation that treat people like objects)
