You can also just null out www.facebook.com in your hosts file and be done with it.

The widgets aren't served by WWW. Try something like to block everything:

  # Block Facebook
  127.0.0.1 www.facebook.com
  127.0.0.1 facebook.com
  127.0.0.1 login.facebook.com
  127.0.0.1 www.login.facebook.com
  127.0.0.1 fbcdn.net
  127.0.0.1 www.fbcdn.net
  127.0.0.1 fbcdn.com
  127.0.0.1 www.fbcdn.com
  127.0.0.1 static.ak.fbcdn.net
  127.0.0.1 static.ak.connect.facebook.com
  127.0.0.1 connect.facebook.net
  127.0.0.1 connect.facebook.com
  127.0.0.1 www.connect.facebook.net
  127.0.0.1 apps.facebook.com

You can also block the widgets without the site (I log in from time to time but haven't seen a widget in a very long time). These days the like buttons are served from connect.facebook.net I believe.
