Jenny Levine, librarian and writer of the blog Shifted Librarian wrote a very thoughtful post about privacy and ownership issues swirling about with Facebook recently.
She argues in her post: Who is managing your online identity?
that it's up to you to take responsibility for your identity and be thoughtful about it. Create it and shape it carefully so that no one else can "steal" it. Don't just opt out of the online world because identity theft can still occur without you knowing it. Apparently, she has no privacy worries as she does post her photostreams to her professional blog.
