Plus using someone else's facebook password can also be considered criminal hacking.
Though Facebook hasn't commented on it publicly: It violates the terms of service of the website/they can close down your account. Whether or not they'd do this: who knows, but they could.
The person has not made the information "publicly available," rather they've restricted access to it via privacy settings. If it were publicly available information, then there'd be no need to gain access to it. Only certain people, "friends" may view this information. So a potential employer demanding access to information just because you showed it to a few friends, makes no sense at all. You told your friends, you did not make it public and specifically took steps to keep the general public from seeing it....
That certain schools aren't teaching cursive anymore is odd. How are you supposed to get a signature? We aren't going to adapt to that one easily if we ever do. This is the problem with short sighted people being involved in education. "O everything's going computerized now, we don't need to teach cursive
." I make it a point to both teach certain children I care about cursive (which their parents appreciate), and to talk to administrators who champion not teaching it. The fact that you admins and all your over-privileged, yuppie friends have neat new smart phones, doesn't mean cursive signatures are dead.
