There was a huge discussion about null strings a few years ago. 
(Probably it was before Andrei, and possibly before your time.)

IIRC, most of the discussion was about detecting the "nullness" of a 
string, and what we should define the Null string to be, there were a 
few good thoughts around the subject in general.
