loewenskind wasn't talking about him personally, but his vision of a world of "open privacy". There are tons of ways I can share my personal life with people: I can call, e-mail, meet up for lunch, bring it up when we're "out", blog about it, etc. Fundamentally, the amount of information I honestly share with everyone I'd possibly run into is quite tiny.
Ug. Apologies, I missed the whole 'vision' part, but I'd been awake for just over 24 hours when I posted that, so my reading skills were somewhat impaired.
