Facebook is becoming a 'couple killer'

Remember at the height of its popularity, MySpace was called a "relationship killer." I thought it was funny at the time, but it's true: Today's social networking sites have led to a lot of arguments between couples, friends and family.

Back in the day, if you wanted to see if your family was lying, you had to call a private investigator. At this point, all you have to do is search the dead man/woman's Facebook wall. Even if someone can skillfully set the privacy Settings to the highest, but now, the difficulty of "caught in bed" has obviously been greatly reduced.
