You know, this makes sense since I recall watching a documentary in the early 2000's about how American Inteligence Agencies were working in creating a "network"of interconnected peers, they got the info from phone usage and emails and they were creating graphical representations of such network, you clicked over some name and it displayed all communications to and from his monitored media. Some time later, after the first boom of Facebook (when no .edu email was needed) I told myself, "well this is actually like that thing these guy were doing"
Now that you point that out, it's obviously easier to give some candy to the people so they can freely hand out their data. I don't use FB to store personal information, not under my real name that is*, but FB it's a great tool for marketing and self promotion when used wisely. So for me is neither good or bad.

The man: Hey you! stop slacking society *bayonet bump* go back to the line and get along, or else
