I stumbled on an interesting article by Caitlin Flanagan in the June Atlantic Magazine. In it Flanagan demonstrates how easy it is to become a cyberstalker. She focuses on My Space and teenagers, but to me the article raises a more basic point: Do you know what you are revealing to random strangers online. The Internet is NOT anonymous and you should be aware of what you are revealing when you go online.
Maybe I should start posting tips for how to remain anonymous but so far there seems to be no demand for it.
Regardless, the least you can do is be aware of what you are revealing and *think* before you reveal all the intimate details of your life.
