Passcodes

I was reading an article yesterday about how people, who are oblivious to security, have placed their private corporate information onto Google Calendar. Google Calendar is secure, if you want it to be, but these folks have decided to make a variety of things public, that shouldn't be.

Here's an example. I typed "passcode" in the search box, and clicked Search Public Events. I was then given a list of hundreds of various conference calls and the passcodes to enter those calls.

I realize that Google Calendar may be a new tool, but why do people constantly surprise me with their level of stupidity? Are we really making better idiots these days?
