Facebook's "Privacy Trainwreck": Exposure, Invasion, and Drama:
"What happened with Facebook was not about a change in the bit state - it was about people feeling icky. It made people felt icky for different reasons - some felt it for the exposure while others felt it for the invasion. Let me explain."

And danah boyd goes on to explain that, in a nutshell, news readers make her feel icky. What this really is about is danah being slapped upside the head by reality and not being able to handle it all at once. Certainly understandable. But what people need to understand right off the bat, is that The Internet is public. Every, every, EVERY bit of it. And just because YOU don't have some nifty little app that lets you make use of that fact, you can be assured that somebody, and most likely many "somebodies", do. The people that signed on to Facebook didn't know that going in and that's their fault, not Facebook's. To borrow danah's analogy, Facebook had the music up loud, but everyone in the room should have realized that the music could stop or change at any moment. And often does and sometimes you don't even realize it.

And I love it that way.
