However, it's common for people to have multiple email accounts, and to 
use them for different things (eg, my work email and my home email 
accounts).  I'm the same person (or, at least I hope I am...), but I 
have two very different "identities".  The foaf file for me at work 
doesn't mention my home email, or home phone etc, and my foaf file for 
my "home" stuff doesn't mention my work email, or work phone.
