Even in our Facebook-obsessed world, some things really are private!  A new study published on itbusinessedge.com, found that more people are ramping up the privacy settings on their social networking profiles than in years past.  Close to 60% of social networking users set their profiles to private so that only their friends can see it- and women actually have more restrictive privacy settings than men.  Sixty-three percent of people have deleted friends from their Facebook profiles; women are also more likely to do this than men.  Maybe guys should take a tip from their female friends- the study found men are almost twice as likely as women to regret posting something to Facebook.
