Common sense tells most that you have to be secure on-line as you would do anywhere else. Lock your doors and shut your windows when you leave the house & don't give your keys to strangers. Sounds easy, but why do people keep making those mistakes on-line? Have we become too complacent in the virtual world that we don't think these rules apply?

LOL I must have read this too fast. When clicking the link, I expected an article about link shortening service and online security. Anyway, it's a good article. Fortunately I don't use social networking sites that much myself.
Yeah, I don't understand those people either. Some of them even have pictures of their kids in their album. I don't think it is very safe to upload you kids' pictures to social networking sites.
