Facebook seems to be one more path to the collective narcicism occuring in this country, which has made us soft, lazy, fearful, and invaded, etc., etc.
You can lock down your Facebook account all the way. I can’t even get friend requests from people. After the initial few real friends I put in before I locked it down so now I can only get suggestions from existing friends to add friends.
After that it’s a great way to keep up with your friends and family, especially if they are as geographically spread as mine.
