"Point your mobile phone at the person speaking at the lectern, the cute person in the bar or that potential recruit and see, hovering around their head, all their social networks, tastes in music and books, and dodgy photos from last night."The potential is quite interesting, but it's also a bit scary, innit? The interesting bit for me is how far this puts pressure on people to be interactive - particularly public figures. There will always be those who either are genuinely open about their life - I know plenty of people who like sharing every detail of their lives.
I think that Westminster may start filling up with people who are ostentatiously open about their lives in a 'look at me I'm a pretty straight guy with nothing to hide' sort of way.
It reminds me of the origins of the word 'Candidate' - from the latin Candidatus - derived in turn from the white robes that Senators wore to signify their purity of mind. It also said 'look at me, I have the wealth and slaves needed to sustain a huge length of clean white linen every day.'
The Man in The White Suit. I would say that 360 degree transparency is something that would be quite expensive to sustain - especially given the huge array of different snobberies that you'd have to be sensitive to.
I wrote a probably-too-long post on things that touch on this question here some time ago if you've got an age to waste.
