I never understood it. I don't really care to know that much detail about people I hardly know, why do they care that much about what I do? Also, it is not safe -- you may think your privacy settings will protect you, but check out news reports (cnbc did a great story of FB not long ago) and you will find that nothing is safe or private. If I want to find out how friends and family are doing, I pick up the phone and call. Or email pictures.
