concerning Facebook and "privacy":

ehem:

When you post something on the Internet, you have POSTED SOMETHING ON THE INTERNET, so it isn't private anymore, you don't own it, and you probably should have kept it on the hard drive, or in your head, or somewhere that isn't ON THE INTERNET, formerly known as THE WORLD WIDE WEB, which doesn't sound private at all, really, seeing as it is WORLD WIDE, monitored by every marketing firm, government "security" agency, corporation, troll, voyeur, plagiarist, and human with an Internet connection, which is just about everyone. So, don't post stuff. Freedom.
