Privacy

As I've written before, I get some of my best ideas and insights from reading what other bloggers have to say.  Today I saw a link to this fascinating article http://nymag.com/news/features/27341/index2.html from New York Magazine on Jenny Levine' The Shifted Librarian blog http://www.theshiftedlibrarian.com/

Librarians have fiercely guarded our customers' right to privacy, and much of the hand-wringing over social networking and other web 2.0 technologies results from what some percieve as the indiscriminate sharing of what used to be considered intensely private information. 

What are the implications if, as this article hypothesizes, a new generation has a very different view of privacy - i.e. that it doesn't exist anyway so why guard it ?
