People don't seem to realise the ecological harm (privacy wise) in using those services. They don't realise that by using those services, they not only harm their own privacy (which is their to shed), but also other's. The sentence "I have nothing to hide" that often gets thrown about has two problems. The first is obvious: whoever says it most probably do have something to hide, and are not quite realising it. The second is much more insidious: it frames the debate individualistically. This is a common flaw in our western societies —see for instance copyright debates talking about one artist and one consumer or pirate. People should realise, as you did, that it is not just about them. I would go even further: using Facebook is not just a personal choice. It's a political one, that affects all around you. Last year for instance, I was forced to use Facebook by friends from my orchestra. I reluctantly set up an account, and kept up for a while. Then I turn off email notifications because they were so annoying. Then I learned, several times, of decisions or events that were discussed only on Facebook, (without my knowledge since I hardly logged in). When they clued in on my ignorance, they said "but I sent the mail" (no you didn't). (I have since "deleted" my account. I won't use that crap ever again) The choice is often between giving up your privacy on Facebook, and being ostracised by such and such group of friends. Disgusting.
