As a journalist, documentarian, … I live my online life pretty openly. At the same time, I am very conscious that we now live in unchartered territories in terms of privacy, and many other online perils. Any powerful enough tools (G+, Facebook, etc) can be used for good and bad (“evil”). It is totally up to us to monitor these tools and to ensure they are used correctly by its property rights owner.
This may sound strange to my economist friends but I believe the traditional economic definition of “property rights” is currently being massaged/redefined.
