I Know Who You Are and I Saw What You Did: Social Networks and the Death of Privacy - Lori Andrews This book is written by an attorney, which places it in the dry and wordy category. However, the information is important enough that it's worth the slog. I scanned much of it that doesn't apply to me, and am gladder than ever that I never joined Facebook and don't share much personal info on the internet. BUT -- "they" can collect info from your most private communications online. Even your e-mails, which we all tend to think are sacrosanct. VERDICT: Every internet user needs to read this book, regardless of whether or not they belong to a social networking site. Yes, it's very thorough, with lots of densely packed small print. But you can easily skip-read the stuff that doesn't apply to you. Meanwhile, for the luvva Gordy, show some restraint in what you post online! ANYWHERE online. Exhibitionism seems to be an unfortunate outgrowth of internet access. Not only is it unseemly, it can come back to ruin your life. It can cost you your job, convict you of a crime you didn't commit, or make you lose custody of your child. It really IS worse than you think.
