Being a lazy user, my first question is: «What is this "3D9AEBB5" thing?
Hm, apparently it is some key, but what key? where did it come from? is
it from gnu.org or what? maybe it is for "keys.gnupg.net" server?  OK, I
should read gpg manual to find it out… but I won't».  And then I will
not check the signature because I trust the tarball from "gnu.org" but I
don't trust a thing that I don't understand.  (I talk only for myself,
I think other people are more conscious users)

I think it will be also good to explain what "3D9AEBB5" means.
