I'm seriously considering account deletion because Facebook is making me uncomfortable. In the past, I've tried to give them the benefit of the doubt -- like when they responded to user feedback and killed beacon. I thought "Gee, maybe they aren't Evil, just a little misguided."
Now, I think they're Evil. The only thing they learned from the Beacon disaster was that they can't roll out all of the privacy erosion at once; you have to do it slowly, so nobody realizes it, or a least their anger never really reaches critical mass. Taking a hint from the government perhaps.
So I'm "hip," as you kids say. But here I am, weighing the benefits of simple and wide-reaching communication against a provider that keeps proving it's willing to sell my information without much warning.
