And at least some "more normal" folk I know (i.e. not security 
professionals) do this too.  There are a number of reasons, but 
commonly having a single "well protected" (by the privacy policies of 
those companies they trust to share the address with) address is the 
reason (the other one is tracking who sell, etc addresses and these 
folk use a separate address for each company/entity that they share 
contact details with).

I've done this for a very long time.  Sometimes the individually-supplied
addresses are rather obviously mine; sometimes they're not.  And I keep
very careful records of which addresses were given to whom.  I've also
trained some other people to do the same.  Sometimes it's very interesting
to note that an address given only to A turns up in B's hands...or B's,
C's, D's, E's, etc. hands in some instances.  There have been any number
of fascinating little case studies demonstrating that data is either
being sold or stolen or otherwise leaked from numerous operations (some
of which predictably claim that this is impossible and that those reporting
same must be mistaken, incompetent, senile or lying).  For instance,
United Airlines has been observed leaking addresses to Brazilian spammers.
