Don't announce my birth on Facebook

Have you seen this article from baby centre?  It's so good!  I've been trying to think of tactful ways to tell my family/close friends that I prefer to make this announcement, not be beaten to it.  I think we are so social media crazed, but I think I might want to enjoy my baby quietly, privately - for just a bit before shouting from the rooftops. This does just that perfectly!
