On another blog someone posted a funny spam letter the pope might get, based on those scam letters from Nigeria that are so common. The Curt Jester has a link to it (see my sidebar to get to that blog.)
Imagine how much email the pope will be getting now. I'm sure he has secretaries to wade through it all, but now that his email is out in public, just think of all the spam! Despite that, I think that his willingness to be so open says a lot about him.
