Slightly OT but interesting. This was true a year ago, unsure if it is still in effect today.
In Gmail, if I send an email to Alice and Bob, but modify Alice's name to "Anne" (or anything else) in the email's "To:" field, and Bob replies all, Gmail saves the change to Alice's contact information in Bob's user list. Alice will now show up as Anne in his google talk and in his contact list.
