+*** Why Antinews is useful
+
+http://lists.gnu.org/archive/html/emacs-devel/2008-11/msg00893.html
+
+The usefulness of Antinews is to help people who buy the printed
+manual and are still using the previous Emacs version.  That's why we
+focus on the (eliminated) behavior of the old version rather than on
+the new features.
+
+Of course, we try to make it amusing as well.
+
+*** Don't mention in Antinews too many features absent in old versions
+
+http://lists.gnu.org/archive/html/emacs-devel/2008-11/msg01054.html
+
+Since the purpose of Antinews is to help people use the previous Emacs
+version, there is usually no need to mention features that are simply
+absent in that version.  That situation will be clear enough to users
+without help from the manual.
+
+For instance, this
+
+    @item
+    Emacs can no longer be started as a daemon.  We decided that having an
+    Emacs sitting silently in the background with no visual manifestation
+    anywhere in sight is too confusing.
+
+may not need mentioning, because --daemon will give an error message
+saying it's not implemented, and other cases aren't affected.
+
+The kind of change for which the user really needs help from Antinews
+is where a feature works _differently_ in the previous version.
+In those cases, the user might have trouble figuring out how to use
+the old version without some sort of help.
