This is a bit off topic for me, but this story discusses the results of a survey of just how many parents spy on their kids' Facebook pages. Survey says ... 60 percent (U.S.). Globally, the average is about 44 percent. Also, a lot more American parents are "connected" to their childrens' social networks than parents in other countries.
And no, I'm not. I can't even see my daughter's FB wall. I'm not "friends" with my son, either, but at least I can see his FB wall if I really want to spy on him.
Oh, and for fun, a map below of the percentage of people by state who use Facebook.
