@briankrebs Back when Facebook was starting to get big, I got an e-mail trying to get me to sign up, and giving me a list of people who I might know.

One of them was the father of the girl I'd dated in high school.

I get how that happened -- people shared their address books, and several people I knew would have had the two of us in common -- but it creeped me the hell out. Felt invasive. A sign of things to come.

I never did sign up for Facebook.
