The privacy we all need on the Internet isn't automatic and it takes a few steps to achieve. I go over some of those I use on my FaceBook page.
Just like you have to intentionally put curtains up on your windows so people can't look in, you have to intentionally make the Internet so others can't spy on you. I'll mention two things that pertain to the Internet as a whole and four that pertain to one of the big privacy threats on the Internet- FaceBook. By the way, I'm not saying FaceBook is evil, just that social networks can be used for evil and FaceBook is one of the biggest social networks.
