even I am increasingly being asked why I am not at least on Facebook or T w itt er, and when I mutter about security concerns folks look amazed.
Just say you have a life and/or better things to do.
My question then is, very simply, how secure are websites like Facebook, T w itt er etc?
It is not about (computer) security but, as you correctly identify, about personal stuff of yours being all over the internet and pretty much a Google search away from anyone. It's every employer's, police force, and tax inspector's dream--not to mention identity thieves and practical jokers (our favourite use at work
).
