And not only, but also..
"The thing is, he’s not alone. Nobody that I’ve spoken to since the LinkedIn hack emerged, even those that are almost certainly affected, has bothered to change their password, and most of them use the same one for everything."
I am not now and have never been a FB user - no plans to change that, unsurprisingly.
