You want edumacating? Or maybe I should leave you in happy innocence...
I've admitted the paranoia. Nobody is going to find anything of any use to them on my computers - not the ones connected to the internet, at least

But when you've been part of a group who were constantly checking out each other's security, you make sure the doors are not only locked and bolted, but hidden as well. I remember the time when one member gloated that nobody could crack his machine... a few hours later a screenshot of his desktop appeared on the forum
You're probably right, freez. Most people wouldn't burgle a house even if the door was left wide open. Even fewer would check to see if it was locked; fewer still would check around the back for an open window. But I wish more people would learn just a little bit more about computer security - then maybe the internet wouldn't be so deluged in spam.
