It's scary how easy it is to find an average persons info online, let alone celebrities.

Google your name and be terrified (unless you have a somewhat generic name)

I got into a mood where I was wondering what happened to people I knew from highschool, a few years ago. I found out way too much information, and none of the information was from social sites.
