I use both key ID and fingerprint even though the key ID is  
redundant.  It lets me avoid explaining to people that the last 8  
digits are the key ID.  As we've seen here, that's not widely  
understood.  Plus, it may not be true forever.  One of the proposals  
for future key formats has the key ID being the *first* 8 digits,  
rather than the *last*.
