The average dude mightnot care yet, but s/he will care in the future. A few years ago it was common practice to participate in mailing lists, forums, etc. using your real name. Then people gradual learned that that had consequences and nowadays nobody really does it. The same goes for posting pictures of you and/or friends and family on an open webpage, nobody does that anymore because people learned the potential problems with doing that. People haven't put facebook and G+ through the same judgement as they have put the internet in general. They still look at it as a place were they can conveniently post personal information. But eventually they will. An interesting phenomenon occurs among adult people that go through a serious relationship break up. Most go back to their private life and abandon their facebook activity for obvious reasons. So I would say, people will eventually care.
