Mark you calendars, because November 17th is National Unfriend Day. It is the day to remove all those people on Facebook (and dare we say Twitter, Myspace, etc.) who are not really your friend.
Sadly I can't participate, since I'm not on any social network (unless you count Buzz....sigh....). But all of you can! Unfriend all those people who really aren't your friend, but just someone you know of or used to know of.
